Elements check

Altair Forum User

Whenever I create a mesh whether it is 2d or 3d,and then I go for elements check I get a question which parameter should I check and correct first (like in 2D first checking warpge then correct all failed elements then check aspect ratio, correct failed elements).Is there any sequence that should be followed to get good mesh and save time??

Thank you.

Depending to your solver, your quality criteron would be different.

But in general of 2D mesh, you can check:

• Jacobian
• Aspect

For 3D mesh, you can add: skew, tet collapse,...

Of course, don't forget to check: connectivity & duplicates

Also, download the e-book 'Practical aspects of finite element simulation' in which mesh quality checks are explained in detail.
