Hi, it is mentioned in several documents that preCICE works with OpenFOAM’s both incompressible and compressible solvers. This sounds reasonable in theory since the only difference is in the force calculation and variable rho. However, my recent tests with rhoPimpleFoam yielded a dimensional mismatch error, which is consistent with some other users (such as here).
I looked up for a preCICE tutorial case utilizing rhoPimpleFoam but could not find it, so now I am trying to set up my own case to be published. I think the best candidate would be the perpendicular-flap case. That will also help debugging the code I believe.
Meanwhile, any ideas on the source of this error would be appreciated.
