Two-side a posteriori error estimates for the DWR method
Bernhard Endtmayer, Ulrich Langer, Thomas Wick
In this work, we derive two-sided a posteriori error estimates for the dual-weighted residual (DWR) method. We consider both single and multiple goal functionals. Using a saturatio…
BDDC preconditioners for a space-time finite element discretization of parabolic problems
Ulrich Langer, Huidong Yang
This paper deals with balanced domain decomposition by constraints (BDDC) method for solving large-scale linear systems of algebraic equations arising from the space-time finite el…
Isogeometric Simulation and Shape Optimization with Applications to Electrical Machines
Peter Gangl, Ulrich Langer, Angelos Mantzaflaris +1
Future e-mobility calls for efficient electrical machines. For different areas of operation, these machines have to satisfy certain desired properties that often depend on their de…
Adaptive space-time isogeometric analysis for parabolic evolution problems
Ulrich Langer, Svetlana Matculevich, Sergey Repin
The paper is concerned with locally stabilized space-time IgA approximations to initial boundary value problems of the parabolic type. Originally, similar schemes (but weighted wit…
Multigoal-Oriented Error Estimates for Non-linear Problems
B. Endtmayer, U. Langer, T. Wick
In this work, we further develop multigoal-oriented a posteriori error estimation with two objectives in mind. First, we formulate goal-oriented mesh adaptivity for multiple functi…
Parallel Block-Preconditioned Monolithic Solvers for Fluid-Structure-Interaction Problems
D. Jodlbauer, U. Langer, T. Wick
In this work, we consider the solution of fluid-structure interaction problems using a monolithic approach for the coupling between fluid and solid subproblems. The coupling of bot…
