Hi everyone,
I am doing FD fan in ansys. I have noticed divergence problem while doing the mass flowrate of 53.54 kg/s and above with IGV 30 deg inclination. I have taken a backup file of the same run while getting diverged in which I have gained some idea that the pressure value at stator-rotor interface is getting too large (around 2 lakh pascal). So that, I have given the interface option as frozen rotor instead stage. And, It is getting converged for the above specified mass flow. I checked the same simulation by changing the interface option as stage through the converged result as initial file. It is also getting diverged and stopped. Is there any problem while doing interface option as stage? or do I have to look any important things before using stage interface? |
