6/13/2023 0 Comments Mesh quality explained![]() ![]() Unfortunately, Hypermesh does not show the element face normals on solid elements, but it is basically an arrow on each face pointing out perpendicular to the face. The Jacobian is a measure of the normals of the element faces relative to each other. It is one number which defines how good or bad an element is. Now more specifically the Jacobian, which is short for the Jacobian Matrix Determinate, is really the best measure of finite element mesh quality. Although, if you do cover it in college you will probably do the actual matrix equations, even though in real life (the business world) a computer does it in fractions of a second. This is so technical that it it typically only covered in senior level college classes or graduate school classes. Bring up a Jacobian to a bunch of finite element engineers and hopefully they will all know what you are talking about. This is as technical as engineering comes.
