    the simple solution that I embrace is to just ditch windows and run linux directly

    if anyone here has used STARCAT5/STARCCM+ in CATIA, what does this error mean? https://cdn.discordapp.com/attachments/400697259819270145/1438319032930668575/Screenshot_2025-11-12_at_7.06.00_PM.png?ex=6916727c&is=691520fc&hm=b44a81fb97418fd4f3b25718e402b0a8fe0f3563511eb39b29c03aa71989b759&

    made a cylinder with one end as a velocity inlet at 1m/s and the opposite end as a pressure outlet, same error

    Just a short question: Do you really want to build a propeller to generate thrust or do you want to cool something as in computer fans?

    If you really want to build this, this really is a multi-stage axial compressor. Then you definately need stator blades to reduce the vorticity entered by the rotor blades. Also the change of diameter is used to keep the axial velocity relatively constant. This is at the end kind compresor design. A propeller is kind of a "single stage" axial compressor but you don't need to remove the vorticity since it only has one stage. If you want to improve the efficiency you still should do this. An example are counter rotating propellers/fans e.g. the CFM Rise engine uses this. I think this not an easy task to start with cfd. I can only tell you that in axial compressor design you would start with mean line design methods to get an initial guess and then start to develop the actual compressor design.

    Within wsl network thingy? Is that a good enough answer?

    rather vague 😁 Not sure about what is going on, I was wondering if this is because you store your folder in a weird place

    \\wsl.localhost\Ubuntu\home\bananaboi i store my work in $FOAM_RUN, so should be fine?

    should be yes, stuff in your home dir isn't supposed to disappear

    Im screaming in despair. Is manually opening paraview the only way to view the mesh? Any scripts?

    You can automate paraview to output images using python

    11/14/2025, 10:41 AM
    From command line without having to open it

    what do you mean by manually opening paraview?
  • z

    Zino

    11/14/2025, 10:42 AM
    Although like, it'll still need to load your data into ram, so it'll be as slow as opening paraview if your mesh is really big

    You can also use tools like PyVista to view the mesh using Python

    I mean, for now i click paraview, run a script in it (often requires processing one case by clicking things then write a script for the others)

    While i can replace that initial setup with some config in a file
