FSI-ALE remeshing with fiber definition

Use Case

I'm implemeting a FSI_ALE simulation of the aorta.

Problem

I have defined the material using HGO model that requires the definiton of two faimiles of fiber. I have noticed that I need to apply a remeshing during the simualtion becasue the movement of the aorta wall lead to distorted elments. However the Simvascualr remeshing alogrithm cannot be applied if fibers are defined.

Solution

Fibers file should be update every time a remeshing is perfomred since the fibers definition is at the level of the element.

Alternatives considered

I don't know if there are software able to do that, since remshing ad material defintion are two challenging problem in this field.

Code of Conduct

• I agree to follow this project's Code of Conduct and Contributing Guidelines

Start by locating the SimVascular remeshing algorithm and the element-level fiber definition handling in the solver. Trace how remeshing changes element data, then determine how the fibers file can be updated after each remesh. Done means remeshing works during an FSI_ALE simulation with HGO material fibers defined.
