Reply To: Fluid structure interaction highly distorted elements

[smm9886]

Dear y21 I am grateful for your prompt and thorough replies to my questions. I am trying to apply the aforementioned strategies to my model to see if it can help me to overcome the highly distorted element error. This is a very time-consuming process; I am not sure if there is something wrong with my numerical setup, but this is taking more than a week to run my models on my computer with 16 cores and 32 GB of RAM. I have tried the Steel structure as the arterial wall and my simulations were running without interruptions for 1 week (when the internet connection in my department has been lost and Ansys failed to process further and aborted due to licensing management error). All in all, I am still trying to modify the mesh to get an optimized model. And, I also think the same that I shall consider defining new materials compatible with nature. However, I could see many numerical simulations of arteries with linearly elastic walls (say E =1 MPa, Nu=0.49). This is making me try to run my primitive models with linear elastic walls. (I am located in Ancona in the middle of Italy. We won't experience that sort of freezing winters that northern parts do (Fortunately)) Grazie tante!
