  1. 262. GPU-Pencil Code integration
    12/08/2019, 09:00
    Matthias and Johannes will be working on the integration between the stand alone GPU-based PDE-solver Astorath and the core CPU-based Pencil-code, to obtain GPU acceleration for existing Pencil Code modules.

  2. 264. Python simulation objects
    12/08/2019, 09:00
    Simon and Fred shall develop the simulation object in the Pencil Code python library. The aim is to be able to utilise the object to manage multiple parameter simulation set-up, compilation, running and post-processing. The existing remeshing routine for changing the resolution, processor layout or grid size of an existing simulation shall be integrated into the pencilnew simulation object.

  25. 278. Lucky Droplets
    Dr Nils Erland L. Haugen (SINTEF Energy Research)
    Direct numerical simulations of collisional aggregation in turbulent aerosols are computationally demanding. Many authors therefore use an approximate model of the collision-coalescence process that is computationally more efficient: it relies on representing physical particles in terms of superparticles. One monitors collisions between superparticles and accounts for collisions between...
