Hi all!

I have a problem with running transient multiphase simulations in patient-specific aortas. I have developped a model using the three-phase euler-euler model, to model blood flow in aortas. I have applied this model on several geometries, and some of them convergence properly, however I also have 2 geometries where divergence occurs. The perculiar thing is that I run the exact same settings for a single phase models (same mesh, boundary conditions etc.) and then everything works fine (no divergence at all).



Does this problem occur more often and where should I try to find the troubles?



Kind regards,



Michelle
