Hey Amine,nYou can ignore the last message. With a bit more working I found it wasn't the settings at at it was the number of processors I had allocated for the local machine in the startup menu. I thought the computer I was working with had 6 but when I set it as 1 it solved the issue must have something to do with how the processors are setup. nThis does mean the solve time per iteration is slower but at least there is no stabilizing pressure message. nHope this can help people that have a similar issue.nThanks for heaps for your help,nSam n
