Involved Codes – iFluids
• Lattice-Boltzmann flow solver• Parallelisation • Steering
– orthoslices– streamlines– remote computations and
rendering (Hitachi, e.g.)– local visualisation– MPI communication

Work in Progress• exploit hierarchy
– very fast first response on interactive changes– successive refinement during interactive communication– smooth integration of HPC batch jobs for accurate analysis– h-refinement (Peano), p-refinement (Adhoc)
