Transient FSI heat transfer using FLUENT and ANSYS
 

We are presently trying to couple both fluent and ANSYS to complete a transient heat transfer analysis. We are attempting to use the mopar command in ANSYS with some success.
We have been able to complete the steady state calculation. However, we are struggling with the transient. We are hoping to only pass flux information intermittently (not every time step).
Can anyone give us some suggestions on how to accomplish this?
