FSI Solver error
 
Hi all,

I'm trying to simulate blood flow using FSI. Anyone know how to reduce the maximum mesh expansion factor?

On the solver screen, it has a ! next to it; meaning it's too high?

Thanks! CC.

mention what kind of mesh and which meshing tool you are using?

Hi Rohit,

I'm using WORKBENCH's CFX mesh.

Hi,

If I am not mistaken, the maximum mesh expansion factor is a measure of the highest jump in mesh size in your mesh. It is possible that your original mesh may already have the high value but if you run FSI simulation, the value will be changed every stagger iterations. So i think you have to check your original mesh and smooth it.
