Default Permeable baffles
Posts: n/a
Hey !
Dealing with a flow in a filter kind of domain, I use permeable baffles to completely separate two regions. There should be a certain pressure drop across the baffles, which I know from experimental data. If I calculate with very low values of Ares and Bres (pressure drop not sensible), I get good solutions. Increasing the values of Ares and Bres, I get more and more of Warning #038, which is
I guess thats the pressure correction equation. Strange is, that in a special range of Ares and Bres, the warnings appear not every iterations, so that some of them will be used to update the field.
My questions are:
- What is exactly happening, or not happening in the iterations with that warning.
- Is there a chance to modify that value of delta = 1.0E-6 for some iterations.
- Do you see a different way of solving that problem

Thanks in advance,
