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.

Thanks

Alley

I had the same problem...it should depend on the initial guess solution. Try to modify the under-relaxation factor. I solved the problem using the coupled solver. Luca
