solving problem !!! need help !!!
I am sloving a flow model in a centrifugal compressor and I have 2 inlet boundary conditions, 1 at the impeller inlet and another at the impeller exit while the outlet is the diffuser exit.
My solver stops half way when it is iterating (after about 30 iterations) and I doubt that errors had occur but have no idea on what is the error. Besides, there are also the model is also facing reversed flow problem. I had tried other method to solve them and they didnt work as divergent occurs: non-positive volume exits and divergent in amg: momentum.
Can anyone please tell me what should I do??
