Dear all,
I'm running simulations for rotor 37 but I have the convergence problem in particular related with the mass equations RMS. The other residuals seem okay. Do you have an idea which parameter I have to vary in order to have the convergency. The simulations are run in steady conditions where the blade turns at -1800 RPM and the shroud turns at +1800 RPM. The value of the mass flow is equal around 0,57 kg/sec per passage. Please let me know how I can fix this problem and if you need some other numerical details let me know as well. Kind regards DD |

Have you read in the documentation about obtaining convergence? Also have a look at the FAQ in this forum (http://www.cfd-online.com/Wiki/Ansys_FAQ).
