Hello Quentin,

It's Norm. residual I think, but I recommend that you can download version 5 and install it, because it will generate a 'residual.csv' file automatically in the directory 'RESU' by calculating with version 5. And you could observe it with Paravis.

Best Regards

Hi,

Thank you xingjian,
For the moment I will not be able to download the 5.0 release. So I try to deal with the norm. residual of the listing file, but the fact is that with an easy case (2D) I do not succeed to have residual under 10^-6 they are like stuck at 10^-4 (even when I switched from low reynold turbulent model to laminar [while decreasing the velocity] and without temperature resolution...).
I really don't know what is wrong with my parameters.. So now I'm like playing with each Global parameters (from the Numerical Parameters menu) to see what happen on the residual.

Best Regards

Quentin
