Dear all,

When I set up my FSI simulation, I want/need my mesh to deform only once the coupling iterations reach convergence.

However, by using SystemCoupling GUI, although implicit mesh update was not ticked on, it is automatically activated, and within a few time-steps (if not the first time-step) my simulation fails.

I am looking for a way to desactivate implicit mesh update during my FSI simulation:

Disable implicit update from TUI command = did not work

The only solution I found useful is: Activate implicit mesh update and set the number of iteration to be very high.

I am running an FSI simulation where fluid to density ratio is equal to 1/ fluid is incompressible and Coupling is performed using the Quasi-Newton IQN-LS(q) method.

Thank you,

Hi Ahmed There is no built in way to do this.
