Unfortunately, there is no simple expression for the mesh element quality that applies to each element type and dimension. The COMSOL Multiphysics documentation contains the following information on the mesh element quality.

"The absolute value of the mesh element quality is based on the ratios of the inscribed and circumscribed circles’ or spheres’ radii for the simplex corresponding to each corner of the element. If the simplex cannot be clearly determined (an apex of the pyramid, for example), the corresponding corner is excluded from the consideration. The absolute value is always between 0 and 1, where 0.0 represents a degenerated element and 1.0 represents the best possible element. A negative value means a contradiction to the COMSOL Multiphysics numbering convention for mesh element vertices (see Element Numbering Conventions), and the element is then referred to as an inverted element."

If you have more specific questions for your particular model I suggest that you contact COMSOL Support.

Thanks, that description from the manual is sufficient for what I want to do.

Could you please point me to the section or page number in the manual where you got that from? I can't seem to find it in any of the documentation that's available when I click on the "help" icon in COMSOL 5.0 .

In the documentation of the 5.1 version you can find this information under Programming Reference Manual > Mesh > Information and Statistics > Quality of Elements.

Hi Aaron,

In COMSOL 5.0, you find it under Quality of Elements on page 252 of the COMSOL Multiphysics Programming Reference Manual.

Magnus,
Where do I find the COMSOL Multiphysics Programming Reference Manual?
Thanks

Never mind, I found it in my start menu!
