Quasi-interpolation in isogeometric analysis based on generalized B-splines

, 2010
Isogeometric analysis is a new method for the numerical simulation of problems governed by partial differential equations. It possesses many features in common with finite element methods (FEM) but takes some inspiration from Computer Aided Design tools.
