Abstract

The high order finite difference method in combination with summation-by-parts operators and weak boundary conditions can very efficiently and reliably handle large problems on structured grids for reasonably smooth geometries. This has been shown in a sequence of papers in the best of journals, where the theoretical tolls have been SBP operators, SAT boundary treatment and the energy-method for stability. The research code for flow calculations using the Navier-Stokes equations based on this technique is currently beeing developed into production status in the EU FP-7 project IDIHOM (Industrialisation of Higher Order Methods). The LiU part consists of a continued theoretical development of boundary and inteface treatment, as well as a major calculation showing this development in practise. In order to deliver this calculation in time and with the proper resolution in time and space we need to have access to the best of computer resources available. Some part of the development so far has been done on Kappa, and we no aim for resources on Triolith.
