Module bempp::quadrature::duffy

Definitions of Duffy transformation rules.

Duffy transformation rules are important for the numerical integration of adjacent alements for functions with weakly singualar kernels as for example in boundary element methods. This module defines Duffy transformation rules for triangular and quadrilateral surface elements. The corresponding formulas can be found in the book Boundary Element Methods by S. Sauter and C. Schwab.
