error at node 0: Divergence detected in AMG solver

Marabelle · September 2, 2013, 12:40

Hello!
Can somebody please help me with this error message? What does it mean? I set the solution methods, boundary conditions etc. as in an example, that I was given and that had been already calculated before. But when I try to start the calculation, I get the following error message:
error at node 0: Divergence detected in AMG solver
I have no idea what it means, so I don't know where to look for my fault.
When initializing, I also get the message:
>>
turbulent viscosity limited to viscosity ratio of 1.000000e+5 in 49400 cells
<<
Maybe that is somehow linked together?
I would really apreciate your answers!

PS: When I stop the calcuation with the cancel button, the program doesn't continue but gets stuck...
