Hello,

I would to perform an ALE-FSI simulation on a model in which two pipes are connected by an internal deformable layer with two holes that allow the flow between the two sides. I was wondering if the internal layer could be represented by shell elements as a membrane or it is mandatory to use solid elements. Furthermore, I would like to know if it is possible to define a hyperelastic model for this layer.
Finally, SimVascular allows to definition of only a tetrahedral mesh. By importing the surface and volume mesh created outside is it possible to use another type of mesh?

Thanks for your time
Valentina

Hi Valentina,

I don't think we add the feature to do FSI with shells. So you should simulate the membrane using a thin solid.
To your other question regarding meshing, I am not clear if I understand it right. But, you're right that SimVascular only creates linear tetrahedral mesh elements. I am not sure if SimVascular can import a mesh - it will definitely allow you to import a model and create a mesh.

Best,
Vijay
