FSI: Import previous solution as intial condition of FSI

kevinyt001 · March 28, 2016, 16:39

Hi all,

I have been using CFX + Transient Structural to get the total mesh displacement of the interface, and it works pretty well.

Recently, I came across a problem that I want to import the previous transient result as an initial condition for the new run. I have saved the .trn file as standard, and I can import it to the CFX when I defines the run in CFX solution.

Unfortunately, no matter what I tried, the solution first comes to the origin. It seems that I don't give enough initializations. What could I do to solve that problems?

I guess I didn't specify the structural initial conditions, but I just couldn't find where to give initial conditions to Transient Structural.

By the way, I am using workbench 16.1.

It is my question too.
