Detailed Description
The MeshEigensystem class actually does not try to check for or fix errors but it provides methods to calculate the mesh's local coordinate system with the center of gravity as origin.
The local coordinate system is computed this way that u has minimum and w has maximum expansion. The local coordinate system is right-handed.

| bool MeshEigensystem::Evaluate | ( | ) | [virtual] |
Evaluates the mesh kernel with respect to certain criteria.
Must be reimplemented by every subclass. This pure virtual function returns false if the mesh kernel is invalid according to this criterion and true if the mesh kernel is correct.
Implements MeshCore::MeshEvaluation.
