Hi everybody,

Frank, you were mentioning that you're working on a compressible FSI version. This sounds most interesting to me.
So far I have been using icoFsiFoam but as Elvis was pointing...

Hi Matteo and Jaas,

How did things work out with your strong FSI solvers? I'm a little bit stuck at the moment. The problem seems to be related to the "moving timestep continuity error" which is...

Hi Matteo, Sorry to bother again....

Hi Matteo,


Sorry to bother again. As I stated yesterday I successfully replaced the SIMPLE section in icoFsiFoam (inside solveFluid.h) by the PISO part from icoFoam and I also implemented...

Hi Matteo, Your points about ALE and PISO...

Hi Matteo,

Your points about ALE and PISO are very interesting. I must state that I'm pretty new to the field of CFD in general and OpenFOAM in particular and am trying to catch up on both...

Hi everybody,

First of all - the traction can be set using tForce.traction() in the setPressure.h. You can see how the pressure and/or traction input is treated in...

Hi Jaas,

Yes, I read Mathieus note in that thread before. I'm not sure what he was referring to by this remark.
