  • OpenFOAM on Debian 12
    In openfoam.org, there is not compiled binaries for Debian (any version). So one should install it using docker (I prefer to do not use it) or by compiling the code from the source. I consider compiling from source, but I do prefer binaries. Source: almost 2 years ago
  • 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: over 2 years 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: over 2 years 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: over 2 years ago
  • command not found and looping
    I suggest you install per the instructions at openfoam.com or openfoam.org instead of using apt. Source: over 2 years ago
