Adaptive time step settings for FSI coupling in ANSYS Workbench for Transient Str

suggalachaitu · June 29, 2016, 09:46

Hi,
I am using FSI coupling using Workbench FLUENT-Transient Structural.
I have given Adaptive time stepping in Fluent..
How should I give the same time stepping in Transient Strutural for its analysis,.. Pls help

Hej,
A bit late, but I do not think you can use adaptive timestepping in system coupling.

I think the system coupling time stepsize, overrides all settings.
(except the mechanical end time). (Both the number of time steps in Fluent and the timestep size).

You can specify the amount of iterations within the coupling iteration, and you can stop and restart your simulation with a different timestep size. Maybe that helps?
