Hi everyone,

for my diplom thesis I'm trying to set up a pulsatile blood flow in a vessel including fluid structur interaction. For this I use CFX and ansys under workbench enviroment. I created the vessel in the design modeler and also used the meshing tools included in workbench. The set up is almost the same like in the cfx tutorial with the oscillating plate. But when I come to run the solver I get an error after some timesteps, that the mesh gets folded. I think I have to do a remeshing everytime the mesh quality gets too low. I'm not able to do this with the documentation provided with cfx. can anybody help me with this? I also tried to set the stiffness of the mesh to 1, which seems to be the lowest, but I would rather like to solve the problem with remeshing.
Do I have to remesh the structure and the fluid domain seperatly, 'cause this is how I generated the meshes in the first place?
I'm confused and need help.


kind regards
Marten
