call Grid_ascReleaseBlkPtr(integer(IN) :: blockId, real(pointer) :: dataPtr(:,:,:,:), integer(IN),optional :: gridDataStruct)
Releases a pointer to allocatable scratch data for a block.
blockId - ID of the block, should be the same ID was used in the corresponding Grid_getBlkPtr call. dataPtr - Pointer to be released. gridDataStruct - an optional argument that designates the type of grid data structure to handle (i.e. facevar, unknown, scratch...)
This implementation actually does more than just releasing the pointer.
