I am trying to obtain a steady state solution of a turbulent case (k-omegaSST). In order to start the simulation with a decent solution, previously to my SS attemps, I run a transient simulation for a quite long time. Then I started my SS solution:



I tried simpleFoam but the simulation crashes at the second step.



Then I tried pisoFoam with localEuler but I get the following error:

Can somebody explain me how to provide rDeltaT?

Try use pimpleFoam instead of pisoFoam ... pisoFoam is for time accurate transient simulations. If your simpleFoam run is crashing on iter 2, then you either need a better starting guess and/or you need to underrelax more.
