Pipe flow FSI using OpenFOAM and CalculiX

Hi @Makis,
I did notice this post on using shell elements. Could this also be a potential issue? I have used shell elements in the Calculix setup.

Perform 2D simulation with Calculix

Hello, I want to perform 2D FSI simulation with Calculix, I saw the test case of the perpendicular flap where the mesh provided has a thickness of 1. What happen if we put a thickness of 0.1 for the solid and we also put a thickness of 0.1 for the fluid domain ? I wanted to know if there is an explanation for this choice of thickness and if this is also working if I want to perform the HRON&TUREK FSI3 for example? I also noticed that you use solid element (C3D8I) for your test case, have you…
