Mesh quality check for VWT
Altair EmployeeIn the introductory video for VWT , it was specified that even if the mesh quality is bad enough still VWT gives quite a reliable solution for the model we are trying to simulate. But it won't be absolute
I want to ask that which parameters in the quality check of mesh do we have to take care of to get the best simulations of a race car(identical to real life)?
Of these mentioned below in the image file

Fine mesh generally gives a better results. But in CAE world, we have to be practical as well /emoticons/default_wink.png' srcset='/emoticons/wink@2x.png 2x' title=';)' width='20'>
The finer we mesh the more compute resources and time it would require to get a solution.

I would suggest following checks:
- Connectivity
-Duplicates
- Min Angle < 5°
- Length < 0.001 (assuming the model is in meters) This check will highlight all elements less than 1mm length.
1 For surface meshing, you will want to resolve any feature on the vehicle with at least 5-10 elements. So if the feature is 100mm then use a 10mm surface element.
These checks would give you a good surface mesh.
