How to improve mesh quality?

Oula · March 6, 2019, 15:04

Hi everyone

I'm struggling a little bit with improving the mesh in my model. I'm using inflation tool to resolve the boundary layer near the walls. The mesh quality stays low after all the attempts to improve it. I got Orthogonal Quality Min= 6.7063e-002 which is bad. So, how can I improve it?, What are the technique that usually used in these cases?.

Any help will be greatly appreciated

best regards

I do agree with AlexanderZ but I also would like to add:
- Check where the lowest quality mesh elements are.
- Try to find out the source of the problem.
- Maybe CAD geometry is faulty.
- Maybe you need finer resolution for your geometry.
