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.

Re: FSI Solver error
mention what kind of mesh and which meshing tool you are using?

Hi Rohit,

I'm using WORKBENCH's CFX mesh.

Re: FSI Solver error

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.
