    Hi!

    Apologies right away if I am asking for too much here, I understand that if
    ever user would ask you how to run the code your inbox would be overflowing
    ...

    But I have a problem with hydro. I atteched an example visualisation to this
    mail. My problem is a jet, inflowing from a nozzle (the red and blue part in
    the image. The jet is impinging onto a half plate or a full plate (half plate
    shown in image the box-like part to the left)

    It seems fine, apart from the "curtain" effect which you can see on the
    isosurface representing a density value.

    I was opting for numerical diffusion at first, but the pattern does not seem
    to make sense. Maybe it is originating from corners at the individual blocks
    ... Using more blocks gives me more ripples and the amplitude is not
    significantely reduced ...

    I am still using FLASH2.1, so my question is basically: did you fix something
    which could cause such an effect?

    Many thanks for your time! I will do my best to try to upgrade to 2.3 when it
    comes out.

    Markus.
