FSI and Remesh

Lezard_Valeth · April 25, 2014, 11:00

Hi all,
When I simulated flow around a cylinder considerating Fluid-Structure Interaction, a error occured because of "folded mesh".
So I want to solve this problem with REMESH method taking advantage of ICEM CFD. But how to do to achieve my idea?

There are examples of dynamic remeshing in the ANSYS Customer website. Alternately your CFX rep will have some examples of it.

" The number of ERROR and WARNING messages exceeds 10000.
Use the /NERR command to increase the number of messages.
The ANSYS run is terminated by this error." I got this error message from the Ansys Out file. What should I do to avoid this?

But I found that the dynamic remeshing is not available for the two-way FSI cases. Do you know other ways to solve my problem?

Fluent will do what you want.

CFX doesnt allow simple method to do dynamic remesh with ANSYS FSI. In order to accomplish this, you need to be well versed in ANSYS APDL, as it requires alot of scripting.
