Initializing transient solution from pre-determined steady state solution

Topspin · March 28, 2014, 17:18

I have to run a heated flat plate simulation many times with slight differences in the heated wall time-varying temperature profile. I'd like to take my already converged steady state .dat file and initialize from that, is that possible?

Yes it is. Load your steady state .cas and .dat file. Switch to transient calculation under General and set up the additional parameters for transient simulation. Save transient .cas and .dat and you are ready to go.

I have confusion about do we need to interpolate steady state solutions by using File > interpolate > read data before running the transient simulation . Or this process is not neccessary ?

Thank You

It is not required
