Hi
I have done some simulations and the intial values used are the default ones. I was wondering when does initial values are important? Is it important to set the relative tolerance for a problem involing linear thermoelasticity and heat transfer? Although my simulation converges at much more lower values than the relative tolerance.

Hi
most of the time I'm rather happy with the solver settings, but also, most of the time I use initial values, that I try to set closer to my best guess of the solution, or that I correct after a first run, because the solver converges quicker like that and my results are overall smoother. All default = 0 is a startingpoint, but not always the best for convergence

Good luck
