A New Technique for the Photospheric Driving of Non-Potential Solar Coronal Magnetic Field Simulations (2016)
Journal Article
Weinzierl, M., Yeates, A. R., Mackay, D. H., Henney, C. J., & Arge, C. N. (2016). A New Technique for the Photospheric Driving of Non-Potential Solar Coronal Magnetic Field Simulations. Astrophysical Journal, 823(1), Article 55. https://doi.org/10.3847/0004-637x/823/1/55

In this paper, we develop a new technique for driving global non-potential simulations of the Sun's coronal magnetic field solely from sequences of radial magnetic maps of the solar photosphere. A primary challenge to driving such global simulations... Read More about A New Technique for the Photospheric Driving of Non-Potential Solar Coronal Magnetic Field Simulations.

Hybrid Geometric-Algebraic Matrix-Free Multigrid on Spacetrees (2013)
Thesis
Weinzierl, M. Hybrid Geometric-Algebraic Matrix-Free Multigrid on Spacetrees. (Thesis). Technische Universität München Technische Universität München. https://durham-repository.worktribe.com/output/1618042

Linear solvers are the motor for many computer simulations that are based on partial differential equations (PDEs). For a wide range of problems, multigrid solvers belong to the most efficient ones. Their convergence rate is mostly independent of the... Read More about Hybrid Geometric-Algebraic Matrix-Free Multigrid on Spacetrees.

Nonsymmetric Black Box Multigrid with Coarsening by Three (2012)
Journal Article
Yavneh, I., & Weinzierl, M. (2012). Nonsymmetric Black Box Multigrid with Coarsening by Three. Numerical Linear Algebra with Applications, 19(2), 246-262

The classical Petrov–Galerkin approach to Black Box multigrid for nonsymmetric problems due to Dendy is combined with the recent factor-three-coarsening Black Box algorithm due to Dendy and Moulton, along with a powerful symmetric line Gauss–Seidel s...

Simulation of Fluorescent Concentrators (2008)
Presentation / Conference Contribution
Bendig, M., Hanika, J., Dammertz, H., Goldschmidt, J. C., Peters, M., & Weber, M. (2008, August). Simulation of Fluorescent Concentrators. Presented at IEEE Symposium on Interactive Ray Tracing, 2008. RT 2008., Los Angeles, California, USA

Fluorescent concentrators (see Figure 1) are developed and investigated in solar energy research in order to improve the efficiency and applicability of solar cells. This is achieved by concentrating even diffuse light on cloudy days on small solar c... Read More about Simulation of Fluorescent Concentrators.
