Solutions dont converge

Hi all,

I’m trying to analyse 4 different types of duct adapters (round to square) but my solutions don’t seem to converge well. Any ideas for improvement?

Here is the project:

Thanks for the help, very much appreciated!


Hello @ketscher ,

By “converge well”, do you mean the residuals? Residuals reaching a specific value, and not reducing further could be due to several reasons mesh quality, boundaries being close to each other, etc. This doesn’t necessarily mean that the solution is not converging.

I would recommend you to also have a look at other plots such as convergence of pressure near the inlet which seems alright.

Hope this would be helpful,
