Abstract
An improvement to the classical application of the isogeometric approach to the boundary element method is proposed. In the classical isogeometric approach the boundary conditions are imposed directly to the control points and not to the geometrical points. Such a position may spoil the results introducing an error. In the present paper a procedure to correctly enforce the boundary conditions is presented and discussed. Comparison with the isogeometric boundary element method is carried out to demonstrate the improved performance of the proposed approach.File in questo prodotto:
