Par-EXPDE: Efficient Object-Oriented Multi-Grid-Methods on Hierarchical Hybrid Adaptive Grids

Project summary

Efficient parallel libraries for the simulation of technical processes are needed in several industrial applications. The difficulty of implementing such a library is to obtain a flexible, easy-to-use and efficient library. This can be achieved by expression templates in C++. Using this concept one can implement a library with an interface which is close to the mathematical language. The aims of the Par-EXPDE project are:

  • Development of an efficient, easy-to-use library for adaptive 3D-multilevel finite element approximations on parallel computers
  • Application of modern programming techniques on supercomputers without loss of performance
  • Simulation of semiconductor and diode pumped solid state lasers
