Grid/GridMain bndPriorityOne [INTEGER] [1] Valid Values: 1, 2, 3 indicates which direction (IAXIS, JAXIS, or KAXIS) gets top priority when applying boundary conditions in corner guardcells We define three values for edges left, center, right, of which center represents interior, while left and right represent the corresponding guardcells. We define a corner where more than one dimension has its its guardcells, so the application must determine which direction gets to fill them. In 2-D, there are four corners: (left,left), (left,right), (right,left) and (right,right). In 3-D case, the following corners are possible : (left,left,left),(left,left,center), (left,left,right),(left,center,left), (left,center,right),(left,right,left), (left,right,center),(left,right,right) (center,left,left),(center,left,right), (center,right,left),(center,right,right), (right,left,left),(right,left,center), (right,left,right),(right,center,left), (right,center,right),(right,right,left), (right,right,center),(right,right,right) bndPriorityThree [INTEGER] [3] Valid Values: 1, 2, 3 the least priority dimension in applying boundary conditions bndPriorityTwo [INTEGER] [2] Valid Values: 1, 2, 3 the second priority dimension in applying boundary conditions convertToConsvdForMeshCalls [BOOLEAN] [FALSE] indicates if appropriate variables are converted from primitive to conserved form during propagation before control is passed to Paramesh for refinement, derefinement, or guardcell filling. This is the old way of ensuring that solution variables are in the correct form for interpolation. It involves unnecessary conversions back and forth and should be obsoleted by the newer mechanism enabled by runtime parameter "convertToConsvdInMeshInterp". The name is a replacement for the old "conserved_var" which many people have found to be very confusing terminology. eosMode [STRING] ["dens_ie_recal_gather"] Valid Values: "dens_ie", "dens_pres", "dens_temp", "dens_ie_all", "dens_ie_scatter", "dens_ie_gather", "dens_ie_sele_gather", "dens_temp_equi", "dens_temp_all", "dens_temp_gather", "dens_ie_recal_gather", "dens_ie_mat_gather_pradscale" determines how to operate on thermodynamic quantities. Possible values are "dens_ie", where density and internal energy are supplied and pressure and temperature are returned; "dens_pres", where density and pressure are given and energy and temperature are computed; and "dens_temp", where density and temperature are given and pressure and energy are computed. Other values may also be available as, depending on whether a multiTemp Eos is used and on implementation of additional physics. For 3T simulations, the best choice is "dens_ie_recal_gather", since this mode will ensure that total energy is conserved when refinement changes occur. eosModeInit [STRING] ["dens_ie"] Valid Values: "dens_ie", "dens_pres", "dens_temp", "dens_ie_all", "dens_ie_scatter", "dens_ie_gather", "dens_temp_equi", "dens_temp_all", "dens_temp_gather", "eos_nop" determines how to operate on thermodynamic quantities for the initial conditions. A call to Simulation_initBlock sets initial conditions on each block, and an eos call follows which ensures the initial values are thermodynamically consistent. The value of eosModeInit determines the mode in which these eos calls operate. Possible values are "dens_ie", where density and internal energy are supplied and pressure and temperature are returned; "dens_pres", where density and pressure are given and energy and temperature are computed; and "dens_temp", where density and temperature are given and pressure and energy are computed. Other values may also be available as, depending on whether a multiTemp Eos is used and on implementation of additional physics. geometry [STRING] ["cartesian"] Valid Values: "cartesian", "polar", "cylindrical", "spherical" Grid geometry geometryOverride [BOOLEAN] [FALSE] whether to bypass some geometry sanity checks - use at your own risk. gr_bcEnableApplyMixedGds [BOOLEAN] [TRUE] whether to enable the Grid_bcApplyToRegionMixedGds interface for implementing boundary conditions with access to the variables of mixed GDSs (in particlular, cell-centered UNK varsiables and face variables). This only has an effect if the GridBoundaryConditions subunit is included and the simulation actually supplies an implementation of Grid_bcApplyToRegionMixedGds. reduceGcellFills [BOOLEAN] [FALSE] smalle [REAL] [1.E-10] Valid Values: Unconstrained Cutoff value for energy smallx [REAL] [1.E-10] Valid Values: Unconstrained Cutoff value for abundances unbiased_geometry [BOOLEAN] [FALSE] attempt to remove floating point bias from geometry discretization.

This applies to interpolation (both "prolongation" and "restriction") in the course of refinement, derefinement, or guardcell filling. This is not yet implemented, but needs to get implemented soon because manually converting in several different FLASH Fortran Grid leads to the possibility of overlooking at least one FLASH Fortran Grid subroutine. derefine_cutoff_1 [REAL] [0.2] Valid Values: Unconstrained threshold value to trigger derefinement for refine_var_1 derefine_cutoff_2 [REAL] [0.2] Valid Values: Unconstrained threshold value to trigger derefinement for refine_var_2 derefine_cutoff_3 [REAL] [0.2] Valid Values: Unconstrained threshold value to trigger derefinement for refine_var_3 derefine_cutoff_4 [REAL] [0.2] Valid Values: Unconstrained threshold value to trigger derefinement for refine_var_4 earlyBlockDistAdjustment [BOOLEAN] [TRUE] If true, let Paramesh redistribute blocks across processors early, so that the block distribution chosen by Paramesh will be in effect when time evolution begins after restart. If earlyBlockDistAdjustment is false, the block distribution enacted by the IO unit when it read a checkpoint file will normally still be in effect when time evolution begins after a restart. This flag is ignored if not restarting from a checkpoint. enableMaskedGCFill [BOOLEAN] [FALSE] When enableMaskedGCFill is FALSE, Grid_fillGuardCells is forced to always ignore optional mask arguments when present in calls. This is the default behavior. Set enableMaskedGCFill TRUE to enable masked guard cell filling. flux_correct [BOOLEAN] [true] turns on or off flux correction gr_lrefineMaxRedDoByLogR [BOOLEAN] [FALSE] Softly force effectively a lower lrefine_max depending on distance from center. See gr_lrefineMaxRedRadiusFact. gr_lrefineMaxRedDoByTime [BOOLEAN] [FALSE] Lower the effective lrefine_max as a function of time.

See x_refine_center, y_refine_center, z_refine_center for the center coordinates. This is approximately (linearly) equivalent to requiring a minimum *angular* resolution, within the limits set by the global lrefine_min and lrefine_max. Only used when gr_lrefineMaxRedDoByLogR is TRUE. gr_lrefineMaxRedTRef [REAL] [0.0] Valid Values: Unconstrained reference time for time-based max level reduction. The effective reduction of lrefine_max only kicks in for times greater than gr_lrefineMaxRedTRef. The first time lrefine_max is effectively lowered actually happens at t=gr_lrefineMaxRedTRef+gr_lrefineMaxRedTimeScale. gr_lrefineMaxRedTimeScale [REAL] [1.0] Valid Values: TINY to INFTY the time scale for effectively lowering lrefine_max: The first reduction takes place at t=gr_lrefineMaxRedTRef+gr_lrefineMaxRedTimeScale. iGridSize [INTEGER] [16] Valid Values: 1 to INFTY Global number of interior cells in the i direction interpol_order [INTEGER] [2] Valid Values: 0, 1, 2 the default interpolation order when using "monotonic" interpolation routines jGridSize [INTEGER] [16] Valid Values: 1 to INFTY Global number of interior cells in the j direction kGridSize [INTEGER] [16] Valid Values: 1 to INFTY Global number of interior cells in the k direction lrefine_del [INTEGER] [0] Valid Values: 0 to INFTY Try to reduce the maximum refinement level by this number of levels on a restart. lrefine_max [INTEGER] [1] Valid Values: 1 to INFTY maximum AMR refinement level lrefine_min [INTEGER] [1] Valid Values: 1 minimum AMR refinement level maxBlockSize [INTEGER] [16] Valid Values: 0 to INFTY max_particles_per_blk [INTEGER] [100] Valid Values: Unconstrained integer if the number of particles in a block exceeds this, it must refine when particle count is a refinement criterion min_particles_per_blk [INTEGER] [1] Valid Values: Unconstrained integer if the number of particles in a block is below this, it must derefine when particle count is a refinement criterion nrefs [INTEGER] [2] Valid Values: Unconstrained refine/derefine AMR grid every nrefs timesteps refRatio [INTEGER] [2] Valid Values: 0 to INFTY The integer refinement jump between levels refine_cutoff_1 [REAL] [0.8] Valid Values: Unconstrained threshold value to trigger refinement for refine_var_1 refine_cutoff_2 [REAL] [0.8] Valid Values: Unconstrained threshold value to trigger refinement for refine_var_2 refine_cutoff_3 [REAL] [0.8] Valid Values: Unconstrained threshold value to trigger refinement for refine_var_3 refine_cutoff_4 [REAL] [0.8] Valid Values: Unconstrained threshold value to trigger refinement for refine_var_4 refine_filter_1 [REAL] [0.01] Valid Values: Unconstrained prevents error calculations to determine refinement from diverging numerically for refine_var_1 refine_filter_2 [REAL] [0.01] Valid Values: Unconstrained prevents error calculations to determine refinement from diverging numerically for refine_var_1 refine_filter_3 [REAL] [0.01] Valid Values: Unconstrained prevents error calculations to determine refinement from diverging numerically for refine_var_3 refine_filter_4 [REAL] [0.01] Valid Values: Unconstrained prevents error calculations to determine refinement from diverging numerically for refine_var_4 refine_on_particle_count [BOOLEAN] [FALSE] if true, the count of particles in blocks act as a refinement criterion refine_var_1 [STRING] ["none"] Valid Values: Unconstrained indicates 1st variable on which to refine refine_var_2 [STRING] ["none"] Valid Values: Unconstrained indicates 2nd variable on which to refine refine_var_3 [STRING] ["none"] Valid Values: Unconstrained indicates 3rd variable on which to refine refine_var_4 [STRING] ["none"] Valid Values: Unconstrained indicates 4th variable on which to refine refine_var_count [INTEGER] [4] Valid Values: Unconstrained count of maximum allowed variable to be used restrictBeforeGhostExchange [BOOLEAN] [True] Whether to restrict all data before small [REAL] [1.E-10] Valid Values: Unconstrained Cutoff value ...

This applies to interpolation (both "prolongation" and "restriction") in the course of refinement, derefinement, or guardcell filling. This is the newer way of ensuring that solution variables are interpolated in the correct form. It avoids unnecessary conversions back and force and should replace the old mechanism enabled by runtime parameter "convertToConsvdForMeshCalls". However, it is only available with PARAMESH 3 or later. derefine_cutoff_1 [REAL] [0.2] Valid Values: Unconstrained threshold value to trigger derefinement for refine_var_1 derefine_cutoff_2 [REAL] [0.2] Valid Values: Unconstrained threshold value to trigger derefinement for refine_var_2 derefine_cutoff_3 [REAL] [0.2] Valid Values: Unconstrained threshold value to trigger derefinement for refine_var_3 derefine_cutoff_4 [REAL] [0.2] Valid Values: Unconstrained threshold value to trigger derefinement for refine_var_4 earlyBlockDistAdjustment [BOOLEAN] [TRUE] If true, let Paramesh redistribute blocks across processors early, so that the block distribution chosen by Paramesh will be in effect when time evolution begins after restart.

This flag is ignored if not restarting from a checkpoint. flux_correct [BOOLEAN] [true] turns on or off flux correction gr_lrefineMaxByTime [BOOLEAN] [FALSE] This parameter activates the ability to manually specify values for lrefine_max as a function of time. You can change the value of lrefine_max a total of 20 times. The parameters gr_lrefmaxTime_N (where N is a number from 1 to 20) tell FLASH the times at which lrefine_max changes will occur. The analogous parameters gr_lrefmaxTimeValue_N (where N is a number from 1 to 20) tell FLASH the value of lrefine_max to use at time gr_lrefmaxTime_N. For example, specifying the following lines in your flash.par file tells FLASH to use an lrefine_max value of 10 at t = 1.0e-09 s and a value of 11 at t = 2.0e-09 s: gr_lrefmaxTime_1 = 1.0e-09 gr_lrefmaxTimeValue_1 = 10 gr_lrefmaxTime_2 = 2.0e-09 gr_lrefmaxTimeValue_2 = 10 .

Data restrictions that happen as part of guard cell filling or within multigrid solvers are not affected by this setting. For PARAMESH 2, this runtime parameter is currently ignored.

This is a switch which determines the action if the number gr_ptRemoveAlgo [INTEGER] [2] Valid Values: Unconstrained integer The algorithm used in determining which particles to remove keepLostParticles [BOOLEAN] [FALSE] Grid/GridParticles/GridParticlesMove gr_ptMaxPerProcBlockFactor [REAL] [0.70] Valid Values: 0.0 to 1.0 When the effective max_particles_per_blk is lowered on a processor because refinement criteria based on the number of particles PER PROCESSOR are used, then the new effective max_particles_per_blk is set to (gr_ptMaxPerProcBlockFactor * pt_maxPerProc). In addition, when the effective min_particles_per_blk is lowered on a processor because refinement criteria based on the number of particles PER PROCESSOR are used, then the new effective min_particles_per_blk is set to (0.5^NDIM * gr_ptMaxPerProcBlockFactor * pt_maxPerProc). gr_ptMaxPerProcBlockNoFuzz [INTEGER] [3] Valid Values: 0 to INFTY A safety margin for estimating the size of basically unpredictable changes of the number of blocks on a processor when remeshing happens. gr_ptMaxPerProcLowerThresh [REAL] [0.0625] Valid Values: 0.0 to 1.0 A threshold.

Convergence criteria:<= max( a_tol^2, r_tol^2 * ). Note: default for a_tol is 0.0, so relative residual criteria is used unless user specifies a_tol, or sets r_tol = 0.0, which means absolute tol only is checked. See also gr_hypreSolverAutoAbsTolFact, for another way of setting a_tol. Currently only used when gr_hypreSolverType is "HYPRE_PCG". gr_hypreAnisoDiffusion [BOOLEAN] [FALSE] If TRUE, we use HYPRE to advance the solution of an anisotropic diffusion problem. This mode is meant to be used for anisotropic thermal conduction in the presence of magnetic fields, hence it is probably only useful for MHD setups. If FALSE, only isotropic diffusion problems are solved with HYPRE (available for both hydro and MHD). ANISOTRTOPIC DIFFUSION IS NOT YET PROPERLY IMPLEMENTED, AND NOT IMPLEMENTED AT ALL FOR AMR. gr_hypreCfTol [REAL] [0.0] Valid Values: Unconstrained If > 0.0, enable in the iterative HYPRE solver an pptional test to see if adequate progress is being made. The average convergence factor is recorded and compared against the tolerance 'cf_tol'. The weighting factor is intended to pay more attention to the test when an accurate estimate for average convergence factor is available. Currently only used when gr_hypreSolverType is "HYPRE_PCG". Example suggested values: something like 0.5, 0.8, 0.9, 0.95, 0.99. gr_hypreFloor [REAL] [1.0e-12] Valid Values: Unconstrained floor value for using HYPRE to advance diffusion. gr_hypreInfoLevel [INTEGER] [1] Valid Values: Unconstrained : Flag to output solver specific information such as Relative Residue, num-iterations. gr_hypreMaxIter [INTEGER] [500] Valid Values: Unconstrained Max iterations of linear solver. gr_hyprePCType [STRING] ["HYPRE_AMG"] Valid Values: "HYPRE_NONE", "HYPRE_ILU", "HYPRE_AMG", "HYPRE_PARASAILS", "hypre_ilu", "hypre_amg", "hypre_parasails", "hypre_none" gr_hyprePrintSolveInfo [BOOLEAN] [FALSE] : Flag to output solver specific information such as Relative Residue, num-iterations. gr_hypreRecomputeResidual [BOOLEAN] [FALSE] If TRUE, don't trust the convergence test until we've recomputed the residual from scratch. This is expensive in the usual case where an the norm is the energy norm. This calculation is coded on the assumption that the accuracy of the residual r is only a concern for problems where CG takes many iterations. Currently only used when gr_hypreSolverType is "HYPRE_PCG". gr_hypreRecomputeResidualP [INTEGER] [-1] Valid Values: Unconstrained If > 0, recompute the residual every gr_hypreRecomputeResidualP iterations. Currently only used when gr_hypreSolverType is "HYPRE_PCG". gr_hypreRelChange [BOOLEAN] [FALSE] At user request, don't treat an approximation of the solution x in the HYPRE iterative solver as converged unless x didn't change much in the last iteration. Currently only used when gr_hypreSolverType is "HYPRE_PCG". gr_hypreRelTol [REAL] [1.0e-8] Valid Values: Unconstrained Relative tolerence r_tol of HYPRE linear solver. gr_hypreSolverAutoAbsTolFact [REAL] [0.0] Valid Values: Unconstrained If not 0.0, automatically set a_tol (absolute tolerance) for the HYPRE iterative solver. If also gr_hypreAbsTol > 0, then the maximum of gr_hypreAbsTol and the automatically determined value is taken. See description of gr_hypreAbsTol for the use if a_tool in the HYPRE solver. If gr_hypreSolverAutoAbsTolFact > 0, then set f = gr_hypreSolverAutoAbsTolFact. If gr_hypreSolverAutoAbsTolFact < 0, then set f = |gr_hypreSolverAutoAbsTolFact|*gr_hypreRelTol. In either case, the automatically determined value for a_tol is f*sqrt( ). Here is a rough estimate of the smallest possible value of the inverse of the diagonal part of the matrix C representing the preconditioner. In that estimate, bfloor is a vector that represents a worst-case tolerable error in b (the RHS of the equation to be solved, A*x=b). Currently, bfloor is set to a vector whose every element is set to gr_hypreFloor. If gr_hypreAbsTol > 0 in addition to gr_hypreSolverAutoAbsTolFact .ne. 0.0, then the maximum of gr_hypreAbsTol and the automatically determined value is taken. Currently only used when gr_hypreSolverType is "HYPRE_PCG". gr_hypreSolverType [STRING] ["HYPRE_PCG"] Valid Values: "HYPRE_PCG", "HYPRE_AMG", "HYPRE_GMRES", "HYPRE_BICGSTAB", "HYPRE_SPLIT", "hypre_pcg", "hypre_amg", "hypre_gmres", "hypre_bicgstab", "hypre_split" : Type of HYPRE solver to be used. gr_hypreUse2Norm [BOOLEAN] [FALSE] whether to use L2 norm for exit condition in iterative solver (instead of L1 norm). Currently only used when gr_hypreSolverType is "HYPRE_PCG". gr_hypreUseFloor [BOOLEAN] [TRUE] whether to apply gr_hypreFloor to floor results from HYPRE. Should probably be TRUE when using HYPRE to advance diffusion, FALSE otherwise. However, flooring will always be turned off when using the HYPRE implementation of Grid_solvePoisson, independent of the value of the gr_hypreUseFloor runtime parameter.

In effect it uses only M=0 multipole moments. mpole_DumpMoments [BOOLEAN] [false] Should the Moment array be dumped at each timestep? Use this option only with care, as the moments will be printed for each radial bin. mpole_IgnoreInnerZone [BOOLEAN] [false] If this is set .true., the inner zone will not be recognized and all inner zone radii will be treated statistically. This can be used only if Lmax is sufficiently low. mpole_InnerZoneResolution [REAL] [0.1] Valid Values: 0.0 to INFTY The resolution spacing for the inner zone in units of the inner zone atomic radius. Two inner zone radii will be considered different if they are more than the resolution spacing apart. A very tiny number will result in a complete separation of all inner zone radii into separate bins. However, the resolution cannot be set to exactly zero, because its inverse value needs to be calculated at some point in the code. mpole_InnerZoneSize [INTEGER] [16] Valid Values: 1 to INFTY The size (radius) defining the inner zone in terms of the inner zone atomic radius.

If set to 'exponential' then the radial equation r(Q) = s * dr * Q^t is used. If set to 'logarithmic' the radial equation r(Q) = s * dr * (e^(Qt)-1)/(e^t-1) is used. mpole_ZoneType_2 [STRING] ["exponential"] Valid Values: Unconstrained Idem for the 2nd radial zone. mpole_ZoneType_3 [STRING] ["exponential"] Valid Values: Unconstrained Idem for the 3rd radial zone. mpole_ZoneType_4 [STRING] ["logarithmic"] Valid Values: Unconstrained Idem for the 4th radial zone.
