Porous baffles in VOF simulations
 
It is said in the User's Guide, that porous baffles are ignored in VOF simulations. But what's the "level of ignorance"? I mean, if the code can't handle them, can I do it myself via user subroutine? Or they will be excluded from the model at the stage of geometry write, so the subroutine will not be called for them?

you can do it on starccm+ with a thin layer of cells (not a baffle), but not in star-cd. VOF is better to do in star-ccm+ anyway. From the user conference demos we were advised not to use star-cd 4 for vof but more star-ccm+. You need to choose the right code...

Well, I'm not going to use Star-CD 4, I'm using 3.24 :)

And I can do it in Star-CD with a thin layer of cells too (actually, two layers - all porous things must be at least two layers thick). But I already have a model with baffles, which I've used for single fluid simulation, so my intention is to minimize model rebuilding.
