Hello All!
I am using Cadence Autogrid/Fineturbo to work on a case of SCO2 compressor. I cannot share much details due to the sensitivity of the project but the issue I am having is: After running around 200 - 300 iterations, I get 'negative density' in multiple domains in run log and residuals shoot up and the flow solver crash abruptly. The mesh is not as per the best criteria but the mesh generation window looks good enough enough overall and doesnot produce any warnings. I am looking for a way to pinpoint exaclty what is causing the flow solver to crash. I have seen some suggestions in different forums to look at the residuals but I am not sure what is the best way to do this. Any suggestions would be very helpful. Thanks, Saugat |
