Mesh Won't Generate

Hello. My problem is that my mesh on Incompressible 7 is not generating due to a problematic edge in my model. On my previous test, (Incompressible 6) the same issue took place, but however, this was fixed after setting the small feature suppression to 1e-5.

But for some reason, when I set it to the same value, it says “Small feature suppression tolerance is too large (more than 15% of the model’s faces were marked for suppression). Small feature suppression was disabled and the mesh will use the original model without suppression.” I decided to increase it - up to 1e-300, but it still says the same thing.

Any advice would be extremely helpful. Thanks!

Hey jviernes,

Thanks for posting on the forum. Give me some time before I take a look at your project, your message and get back to you!

Hi @jviernes,

It seems like you were able to generate the mesh for your model, could you share with the Community how you managed to do it?

As a sidenote, it’s better to simply remove these problematic issues in a CAD tool instead of having them fixed by the Small Feature suppresion. Looking at the meshing log, the Non-orthogonality for your model is still pretty high and this will likely lead to instabilities in your simulation.

Going to the Mesh quality viewer, you’ll be able to spot potential candidates for cleanups:
