FSI solver for compressible flow
 

Hello , I am a fresher in OpenFOAM. I have to do an FSI problem for a wing in a compressible flow. can anybody suggest me which solver i should be using.

I have tried in icoFsiFoam and icoFsiElasticNonLinULSolidFoam, since both are used for incompressible flows, I cannot use them.

Can anybody kindly help, Please

I think you are going to need to edit icoFsiElasticNonLinULSolidFoam to make it compressible. I would resist using icoFsiFoam because I think it doesn't work in parallel.

If you look inside the solver the code inside the solveFluid.H is identical to icoFoam, you might be able to quickly make a solver by pasting the code from something like rhoPisoFoam into there and pasting the extra fields from that compressible solver into createfields.H.

sorry for the delay. I tried to add rhopisofoam to the icoFsiElasticNonLinULSolidFoam but the solver is not building in foam extend. it shows error. Is ther any thing i can do.
Thankyou

I wish I could help more but I am new aswell. icoFsiElasticNonLinULSolidFoam doesn't actually run in parallel, I have tried with proper HronTureckvalues and that doesn't work even with 2 cpus, also doesnt work on my own test geometry, and the solidMechanics support thread has several people with the same problem.



If you only want a steady state solution anyway then I would use icoFsiFoam and follow this report/tutorial:

I have got cavitatingFoam(compressible solver) to work with it.



the instructions work with foam-extend 3.1 mostly, but something needs to be done differently for it to compile, I think it was in createStressMesh.H.


If you want to edit icoFsiElasticNonLinULSolidFoam then maybe you could post the code or tell the forum the compile error your getting?
