True Impact of Using "Relax Mass" Expert parameter for transient runs
I'm attempting to start a transient solution using a res file for initial conditions and I get an overflow error around the 3 coeffiecient loop of the first timestep. I thought perhaps applying a relaxation to my solution may help the startup of the run.
Upon reading the CFX help I noticed that under the help section for "relax mass" it statest that default is 0.75 but then in the description it states Quote:
Anybody have better insight into this? Further does anyone have any advice as to what relaxation settings might help the startup of my run? Thanks. |
You would have to discuss it with CFX support to get details of exactly what is happening. Full details of expert parameters are not published.

I appreciate the reply ghorrocks. I guess I'm not looking for anything in detail, but rather a summary statment as to what the effects on my results would be if I were to use this relaxation in transient runs.
But you are correct that probably my best avenue will be to contact ANSYS support. |
