The method is unconditionally stable and has second-order accuracy in time. We extend the second-order generalized-method to third-order in time while the numerical dissipation can be controlled by a single parameter. In each time step, the scheme only requires inverting one matrix on ...
Generalized-alpha methodThe isogeometric analysis boundary element method (IGABEM) has a broad application prospect due to its exact geometric representation and good approximation properties. In this paper, a novel radial integration IGABEM (RI-IGABEM) based on the generalized- method is proposed to...
