what is the phisics of your subdomain? I use a symmetry boundary condition for a fluid and plane symmetry (corrisponding to the goemetry plane's symmetry) for a solid.
I was in error... for activate the fluid motion i set to the interface a pressure type boundary condition with (Tax_smsld,Tay_smsld,Taz_smsld)...so now the problem is that the fluid is strongly turbulent and the solution converge only for too small force applied to the diagphram... i need to...
Hi,
I've got a strange doubt.I model an elastic diaghfram that move water in piping system (a simple pump) so I've got used the 3D FSI multiphicis. Note that in Comsol's examples is the fluid that move the solid structure: i use the same procedure but for the opposite case.
I create a simple...
