Main Goal

A main goal is the development of a General Adaptive Differential Equation Solver, including mathematical basis, mesh generation and CAD. Key features are:

  • generality of models: coupled multi-physics modeling combining phenomena from solid mechanics, fluid dynamics, electromagnetics, reaction-diffusion. Differential-algebraic models.
  • generality of discretization: space-time h-p finite elements in 2d and 3d, stationary and non-stationary, moving boundaries,...
  • automatic quantitative error control in arbitrary norms, based on a posteriori error estimates including stability factors computed by solving linearized dual problems,
  • efficiency: multigrid, explicit/implicit, parallelization,...
  • CAD: coupling of the general solver to advanced tools for geometric modeling such as ProEngineer,
  • mesh-generation: adaptive mesh refinement within the solver with updating of CAD geometry, and coupling to mesh generators (e.g. the in-house mesh generator M3d),
  • optimization, including feed-back to CAD,
  • automatic modeling: computational based subgrid modeling,
  • applications to fluids, solids, electromagnetics, chemistry, and multi-physics, including aspects of optimization and automatic modeling. realization of the general solver on different levels of complexity for educational purposes.

Building blocks

Our research has three main components, Theory, Applications and Software.  

Theory

Our focus is finite element analysis, especially a posteriori error estimation and adaptivity. We are also active in the fields of computational modeling, optimization and large-scale industrial problems.

 

Applications

Application areas of special interest are

Electromagnetics
Mechanics
Chemistry
Material processing
Multi-physics
 

Software

We are working on a general solver capable of handling complex geometries and large-scale problems. Although very capable and rich-featured, the current state of the solver is "in-house".
