Diverging Velocity Field

Project Support

Hi

So, as the title suggests, the velocity field started to diverge. I tried refining that area but it says certain mesh qualities/metrics were still within the recommended range. I’m still pretty new to CFD in general so I am not exactly sure how to approach this problem and hopefully anyone knowledgeable about this (especially SimScale support) can assist and point out what I have to do. Thanks. Screenshots with descriptions below:

This one says I have quality metrics outside the recommended range (probably what’s causing the velocity field divergence)

Hello,

I’d suggest that you follow typical troubleshooting steps here. If you follow the steps carefully, you will notice a handful of very small faces around the divergence point, which I would suggest that you clean up in the CAD model.
