mass convergency problem
 
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).
