icoFsi with topology change in both solid and fluid domain
 

Hello, guys

Right now I'm using icoFsiFoam to model fluid flow and solid deformation and damage. I have topology change in both fluid domain and solid domain. For fluid domain, I have layer addition in the dynamicmotionsolverFvmesh, which allow me to add layers and points. I can see the points added on the patch boundary, however, when I check "motionU", which is tetpointvectorfield, it does not update after points added, giving me the segment fault. It seems that the number of tetpoint does not update. I'm wondering is it possible to update motionU after adding points on the patch?

Thank you.

icoFsiNonLinULSolidFoam mesh topology change
 

Hello Dear


I am using icoFsiNonLinULSolidFoam solver for simulating the one way valve.

Because of extreme change of valve's throat , DynamicMotionFvMesh class is not a good scheme for my case. I want to know that , can this solver support other dynamic scheme defining in foam-extend-3.1 ( for example dynamicTopoFvMesh or dynamicRefineFvMesh , etc) for re-meshing or refining the regions that have bad meshes during solution .


Could you help me to solve this problem


Best Regards
