Hi everyone, I'm trying to follow this youtube movie tutorial:
https://www.youtube.com/watch?v=DGPmyGFnzhA
I'm working with carotid arteries , but before I was considering the artery rigid and I only simulate the fluid domain. Now I want to enter the FSI simulation, but I have a problem, I'm using FEMAP to create the geometry (my fluid domain, who is a solid body part). But in the tutorial, for the transient structural your geometry part is divided in a solid part, for the fluid domain and a surface body part for the solid domain. I already tried to create the surface from my solid body part using ANSYS but it replaces the solid part for the surface body part. How do I create these two different body parts, using the solid part? Or can I use the two geometries individually? My solid part is divided in all the surface structures of the artery, including the boundary surfaces CCA, ICA and ECA. Is possible, if I manipulate the ANSYS and use the solid part for the fluid domain and the surface part for the structural? Or the geometry must be divided in the two different parts, to work? Can anybody help me?

Thanks in advance!
