Dear all, <\/p>\n

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

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.<\/p>\n

I am looking for a way to desactivate implicit mesh update during my FSI simulation: <\/p>\n

Disable implicit update from TUI command = did not work <\/p>\n

The only solution I found useful is: Activate implicit mesh update and set the number of iteration to be very high. <\/p>\n

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. <\/p>\n

Thank you,<\/p>\n","protected":false},"template":"","class_list":["post-161119","topic","type-topic","status-closed","hentry","topic-tag-dynamic-mesh","topic-tag-systemcoupling"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
