How can larger spatial domains be simulated over longer time periods?

Schematic view of the use of an adaptive grid for the simulation of laser ablation (subproject B.5).

 

In many projects of the SFB 716, more and more accurate results could be achieved if simulations could be performed on larger spatial domains and for longer time periods. This holds, e.g., for subproject B.5 (laser ablation) and C.5 (macromolecular transport in nanoscale pores).

One approach to achieve such domain extensions is the use of dyanmically adaptive computational grids. In particular tree-structured grids are very memory efficient and highly scalable on parallel machines. The challenge, however, is to integrate such grids in a minimally invasive way with minimal efficiency losses in application codes.

The Subproject D.8 develops and implements such an integration concept using example applications from the collborative research center (among others B.5 and C.5) that face an urgent need to extend the domain and time period. This requires new developments in the field of modelling, discretization, data structures and data access algorithms, parallelization, and visualization.
