FSI with remeshing
 
Hi all
I am trying to simulate Vortex induced vibration of a body with 2 way FSI in ANSYS workbench. can i use remeshing with FSI simulation? how can i do? is it (remeshing) necessary?
when i have to use remeshing in FSI?


Thanks, best regards.

Remeshing within 2-way FSI is not supported.

Remeshing in moving mesh simulations might be needed if you have strong displacements in your domain. On some cases elements become so distorted that they get inverted. The solver will then exit with a 'negative element' type of error.

Remeshing in 2-way FSI is generally not supported because the solver needs to re-interpolate FEA and CFD meshes, but I believe ANSYS has come up with a beta feature (ie, try on your own risk) for R13 that will allow you to do that. Talk to your ANSYS representative and ask for an example.

Cheers.
