Averaging Techniques for a Posteriori Error Control in Finite Element and Boundary Element Analysis and efficiency of the introduced estimator results from two grids . . and . . with different polynomial degrees for a smooth exact solution. The proofs are based on first order approximation operators and inverse estimates. For a finer and finer fine mesh . ., the estimator becomes asymptotically eADORN 发表于 2025-3-25 22:08:32

Sparse Convolution Quadrature for Time Domain Boundary Integral Formulations of the Wave Equation bture method in time, developed by Lubich. In space, a Galerkin boundary element method is considered. The resulting Galerkin matrices are fully populated and the computational complexity is proportional to . log. . ., where . is the number of spatial unknowns and . is the number of time steps..We pr意外 发表于 2025-3-26 11:48:13
