The quality of elements in a mesh can be gauged in many ways, and the methods used often depend not only on the element type, but also on the individual solver used.  When possible, the most common or standard methods are used, but there is no truly standardized set of element quality checks.  The different methods of calculating element quality are broken down here by solver (such as Nastran).  Each application-specific topic includes information for both 2D and 3D element quality checks, as appropriate.  However, only the checks actually used within HyperMesh by that solver are described in the following topics; when a solver does not support a specific check within HyperMesh, HyperMesh uses its own method to perform the check.  This means that, for example, when using the NASTRAN checks, many of the checks that you see on the Check Elements panel are described in the Element Quality Checks: HyperMesh topic rather than the Element Quality Checks: Nastran topic.
