Question

Press Fit Contact analysis with thermal load, finite friction and large deformation (CREO4)

I'm experiencing insanely long run times (36+ hours) when trying to run this analysis.  When I change the contacts to infinite friction it runs in about 1.5 hours.  My hunch is that there's a simple check-box I'm missing or there is some other simple reason this is happening.  I need to use finite friction to get realistic results but I can't wait 2 days per run.  Any ideas?

Thanks.  But the problem I'm having is that I'm getting very different stress results from a colleague using Nastran.  I'm trying to dial CREO in to get similar results.  In other words, I don't trust the results.  In the CREO 4 case, my stress results are much lower than expected.
