Journal ArticleDOI
Boundary Element Tearing and Interconnecting Methods
Ulrich Langer,Olaf Steinbach +1 more
TL;DR: The first numerical results confirm the efficiency and the robustness predicted by the analysis, and there is an unified framework for coupling, handling, and analyzing both methods.
Journal ArticleDOI
Numerical analysis of nonlinear multiharmonic eddy current problems
TL;DR: A rigorous estimate is provided for the total error that is due to the use of truncated Fourier series, the regularization technique and the spatial finite element discretization in non-linear eddy current problems.
Journal ArticleDOI
Space–time isogeometric analysis of parabolic evolution problems
TL;DR: In this paper, a stable space-time Isogeometric analysis (IgA) method was proposed for numerical solution of parabolic evolution equations in fixed and moving spatial computational domains.
Journal ArticleDOI
Finite-element simulation of wave propagation in periodic piezoelectric SAW structures
M. Hofer,N. Finger,Guenter Kovacs,Joachim Schöberl,Sabine Zaglmayr,Ulrich Langer,Reinhard Lerch +6 more
TL;DR: Two newly developed PBC algorithms are developed that deliver the same results but have totally different numerical properties and, therefore, allow the use of problem-adapted solvers.
Journal ArticleDOI
Geometry + Simulation Modules: Implementing Isogeometric Analysis
Bert Jüttler,Bert Jüttler,Ulrich Langer,Ulrich Langer,Angelos Mantzaflaris,Stephen E. Moore,Walter Zulehner +6 more
TL;DR: G+SMO (Geometry+Simulation Modules), an open‐source, C++ library for IGA, an object‐oriented, template library, that implements a generic concept for I GA, based on abstract classes for discretization basis, geometry map, assembler, solver and so on.
