Classes
class	Linearizer
	Linearizer is a utility class which converts a higher-order FEM solution defined on a curvilinear, irregular mesh to a linear FEM solution defined on a straight-edged, regular mesh. This is done by adaptive refinement of the higher-order mesh and its subsequent regularization. The linearized mesh can then be easily displayed or exported to standard formats. The class correctly handles discontinuities in the solution (e.g., gradients or in Hcurl) by inserting double vertices where necessary. Linearizer also serves as a container for the resulting linearized mesh. More...
class	Orderizer
	Like the Linearizer, but generates a triangular mesh showing polynomial orders in a space, hence the funky name. More...
class	Vectorizer
	"Vectorizer" is a Linearizer for vector solutions. The only difference is that linearized vertices are vector-valued. Also, regularization of the resulting mesh is not attempted. The class can handle different meshes in both X and Y components. More...
