Fluid-structure interaction of a rod in 3D

Please login with a confirmed email address before reporting spam

Hello,

Comsol has a 2D Fluid-Stucture interaction example in it's application gallery such that a filament in a 2D channel gets deformed once it's subjected to fluid flow https://www.comsol.com/model/fluid-structure-interaction-361. My model is pretty much similar to that example but I am trying to build it up in 3D. However, my 3D simulation is being run but not converged correctly. I tried different type of solvers but think my "Model Builder" setup may need more sections to be added. I will appreciate any suggestions and if anyone can help?!

Bests
