two-way FSI

Shabi1992 · April 22, 2016, 23:56

Does anyone have experience with 2-way FSI in Ansys?

I want to insert velocity=cos(2pi*time) for solid in transient structural but when I choose the body and want to insert velocity,I can only insert the number not expression... How can I insert v=cos(2*pi*t) in transient structural??

thanks

If you want to move the body rigidly with that function then this is a rigid body simulation, not a FSI simulation.

If you want to move a part of the body with that function and the body flexes with inertia and/or fluid load then this is a FSI simulation. In that case have a look at the ANSYS Workbench/Mechanical documentation. ANSYS Mechanical has a similar syntax to the CEL in CFX, but it is different so you need to look it up to get it right.

thank you very much
