  • Please help me get running OpenFOAM
    Hello I am a mechanical engineering student in my last year. So I made the wisest decision to learn OpenFOAM. But there is the catch. I have no idea how to use Linux or how to emulate Linux on Windows 10. I found a lot of videos on Youtube how to download an start OpenFOAM but every one of them was using different methods each time so I got confused. Can anyone please help or direct me? Thank you for your answers... - Source: Reddit / about 1 month ago
  • Step by Step (Written not Video) Tutorial for FEM with Air
    As far as air flow simulation, I got slightly farther with Open Foam than I did in FreeCAD directly. Still, I got in way over my skill level and stopped before getting anything useful. - Source: Reddit / about 2 months ago
  • Open source FEA tools instead of ANSYS Workbench and APDL
    There are two versions of openfoam, one closed source (which is the one I linked to in my original comment, my apologies about that) and the open source version. But what you're describing makes it sound like fenics might be your best option. - Source: Reddit / 2 months ago

  • OpenFoam installation issue
    If you haven't used the ESI version (i.e. If you got it from , let me know because the setup is much easier imo. - Source: Reddit / 4 months ago
  • What is the drag coefficient of a rubber ducky?
    For more complex shapes you need to solve the nonlinear navier-stokes fluid dynamics equations which can be done using some fluid dynamics software that uses the finite elements method. This is not a trivial task to do as the solutions are very sensitive to computational parameters (and they are very computationally expensive as well), so you need to know-how. While there are free open source fluid dynamics... - Source: Reddit / 6 months ago

  • Easy to use physics simulation software
    You have to look into CFD software. Most are going to be really expensive for private use, but there are some decent open source options like OpenFOAM. - Source: Reddit / 10 months ago
  • I designed a modern Racing Broom in CAD. thoughts?
    When I was in college, my university offered a free license to Autodesk and COMSOL. They are quite pricey if you don’t have that kind of access. But here’s an open source version: - Source: Reddit / 10 months ago
  • Is there a simple and free software to simulate heating water in pipes? (Details below)
    Open Foam is free and has the 3D solvers for all of that, although I wouldn’t call it simple to use. - Source: Reddit / 12 months ago
  • Best way to run OpenFOAM on Windows
    Having previously used OpenFOAM on Linux over the years, I've been asked to consider switching to Windows. I'm using the OpenFOAM Foundation version, from From what I've read so far, there are 2 realistic avenues for installation of OpenFOAM on Windows (please feel free to correct me/add upon these options). - Source: Reddit / about 1 year ago
  • Porting a case from to
    The title pretty much says it all I need help porting a case from to The case in question doesnt run on the .org version. I found a solution the other way around here but thats not helping my problem. - Source: Reddit / about 1 year ago
  • 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 / over 1 year 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 / over 1 year ago
