divergence detected

German Montalvo

I am working in a compressor stage, I am trying to validate the model with results of other software CFX, so replicated the whole model in terms of the geometry and boundary conditions as well initial conditions, though after a few iterations the simulations stops with the following error message "Error: divergence detected in AMG solver: temperature" I check everything over and over but seems that the problem is not there, though I noticed temperature and pressure limited in the volumes of my model. So I wonder if anyone could help me out on this in order to figure it out.

Thanks in advance.
