Functional a posteriori error estimates for parabolic time-periodic boundary value problems
Ulrich Langer, Sergey Repin, Monika Wolfmayr
The paper is concerned with parabolic time-periodic boundary value problems which are of theoretical interest and arise in different practical applications. The multiharmonic finit…
Multipatch Discontinuous Galerkin Isogeometric Analysis
Ulrich Langer, Angelos Mantzaflaris, Stephen E. Moore +1
Isogeometric analysis (IgA) uses the same class of basis functions for both, representing the geometry of the computational domain and approximating the solution. In practical appl…
Numerical Simulation of Fluid-Structure Interaction Problems with Hyperelastic Models: A Monolithic Approach
Ulrich Langer, Huidong Yang
In this paper, we consider a monolithic approach to handle coupled fluid-structure interaction problems with different hyperelastic models in an all-at-once manner. We apply Newton…
Analysis of Multipatch Discontinuous Galerkin IgA Approximations to Elliptic Boundary Value Problems
Ulrich Langer, Ioannis Toulopoulos
In this work, we study the approximation properties of multi-patch dG-IgA methods, that apply the multipatch Isogeometric Analysis (IgA) discretization concept and the discontinuou…
Discontinuous Galerkin Isogeometric Analysis of Elliptic PDEs on Surfaces
Ulrich Langer, Stephen Edward Moore
Isogeometric analysis uses the same class of basis functions for both, representing the geometry of the computational domain and approximating the solution. In practical applicatio…
