Parameterized Uniform Complexity in Numerics: from Smooth to Analytic, from NP-hard to Polytime
Akitoshi Kawamura, Norbert Th. Müller, Carsten Rösnick +1
The synthesis of classical Computational Complexity Theory with Recursive Analysis provides a quantitative foundation to reliable numerics. Here the operators of maximization, inte…

Simulation of a moving liquid droplet inside a rarefied gas region
Sudarshan Tiwari, Axel Klar, Steffen Hardt
We study the dynamics of a liquid droplet inside a gas over a large range of the Knudsen numbers. The moving liquid droplet is modeled by the incompressible Navier-Stokes equations…

Adaptive finite elements with anisotropic meshes
Weizhang Huang, Lennard Kamenski, Jens Lang
The paper presents a numerical study for the finite element method with anisotropic meshes. We compare the accuracy of the numerical solutions on quasi-uniform, isotropic, and anis…
