Under-relaxation of PISO
 
I'm interested in what actually does UEqn.relax() in pisoFoam ?
It stabilized (accelerated) my comptutation of the thermo flow in a channel and the phase change liquid-solid a lot, but I do not know if the solution is correct, I mean the transient solution, not the steady-state one.

Thanks for any help,

Gregor

UEqn.relax() exists in pisoFoam. but there is no p.relax(), Im confused too. Did you find a solution?

Not yet, unfortunately.

With regards.
