  • Looking to build a PC for Computational fluid dynamics - Budget around $2000 CAD
    Mostly for work. I need to run some CFD models (OpenFOAM - But I also need to do pre-processing to create the models. I will use YADE ( and GMSH ( for this. I think that for OpenFOAM it is more important to have good processors but for YADE and GMSH I think that I will also need a decent GPU. - Source: Reddit / 28 days ago
  • If I were to want to mathematically model a human circulatory system, what would be the best computer programming language to use?
    I don't know much about your field, but I would probably start with something like OpenFOAM. I believe it is C++, though there may be bindings for other languages I am not aware of. - Source: Reddit / about 1 month ago
