Career path

Education

Personal Information

Starting in June 2019, Vadym Aizinger is the Professor for Numerics of PDEs at the University of Bayreuth.

He obtained his PhD at the University of Texas at Austin in 2004 followed by postdoctoral fellowships at the Universities of Heidelberg and Frankfurt as well as at the Max Planck Institute for Meteorology in Hamburg. In 2012-2017, he held positions of a lecturer and a substitute professor for Scientific Computing at the University of Erlangen-Nürnberg; in 2017-2019, he changed to the Alfred Wegener Institute in Bremerhaven where he headed the 'High performance computing and data processing' group. He habilitated in 2019 at the University of Erlangen-Nürnberg.

Competences

The main research interests of Vadym Aizinger are the mathematical modeling and numerical methods for simulation of various PDE-based problems in climate and environmental sciences.

His special focus are large-scale applications, in particular, numerical models of coastal, regional, and global ocean that

• are based on a finite element or a finite volume method -- his personal favorite is the discontinuous Galerkin method and variations thereof
• use unstructured or block-structured meshes
• require massive amounts of computational resources

• Modeling of climate and its compartments

Topics and methods

The main focus of my work is the development, analysis, and application of numerical algorithms and discretization schemes for simulation of physical, chemical, and biological processes in environmental and climate applications. The systems being simulated are usually characterized by very large domains with complex geometry; the spatial and temporal scales are highly heterogenious: the simulated phenomena can have sizes between meters and thousands of kilometers and durations from fractions of a second to centuries. These considerations set a very high bar for mathematical modeling skill, efficiency of the numerical methods, and high performance computing (HPC) proficiency.

The discontinuous Galerkin (DG) finite element methods offer many desirable properties that make them an attractive choice for environmental and climate models. These include

• robustness for low-regularity problems such as those with shocks and discontinuities;
• guaranteed local conservation of all unknowns;
• natural support for arbitrary order approximation spaces;
• non-conforming meshes and hanging nodes present no difficulty;
• easy accommodation of h- and p-refinement;
• local approximation stencils highly suitable for parallel computing.

A relatively high computational cost of DG discretizations compared to the classical finite elements or finite volumes of the same order can be partially offset by superior parallel scaling of DG schemes. In addition, a number of strategies appear to hold promise with regard to increasing method’s efficiency and accuracy

• mesh adaptivity allows to efficiently utilize computational resources and obtain a more accurate solution in the areas of interest;
• locality of DG approximation stencils improves parallel scalability on HPC clusters and hybrid computational architectures;
• approximation space adaptivity permits very high accuracy without excessive computational cost in parts of the computational domain, where the analytical solution is smooth, and relies on low-order approximations otherwise — all this without violating the local conservation properties of the scheme.
