Posts: n/a
Hello everyone

I am solving a two phase flow problem in pipe with Eulerian model. when i initialize my case and start itertaions it gives a message of divergence detected in AMG solver: pressure correction at first iteration. I do not understand this message. Can anybody explain me this message.
