farhan97 is on a distinguished road
I am trying to simulate blood flow through an artery using a Transient structural-Fluent coupling system. The simulation runs fine for Steel as Engineering Data. But when I change it for artery (very small Young's Modulus), the error saying "Excessive distortion on solid domain" shows up.

I have followed previous threads similar to this and tried changing step size and mesh size but it did not help.

Can anyone help who has solved this problem? Thanks!
