Hello,

I have several questions on Altair UltrafluidX:

Does UltraFluidx only work on Rocky Linux?
I have an Nvidia GTX1650, would that suffice?
Where is the virtual windtunnel that I can send the job to ultrafluidX? I cannot find the download file and also cannot find it in the installer. (See attached image)
How do I access this tutorial?
Are there more tutorials and installation guide on Ultrafluid X?

Thank you.

You will need the HyperMesh CFD and CFD Solvers packages. Setup is done within HyperMesh CFD.

That GPU has only 4 GB RAM - so maybe you can do some very small models. Anything more industrial typically requires multiple (4 to 8) high-end GPUs - A100, H100, etc.

This is a good starting point for a UFX tutorial.

Thanks, Acupro.

However, I still cannot find the "hwVirtualWindTunnelUltraFluidX2025.1_win64.exe" file mentioned in the user guide, and when I launch HyperMeshCFD, it directly takes me to the General purpose CFD - Acusolve.

Could you please tell me what the fix is?

I do not have this option:

Hakan_20716

This interface is now obsolete. Make the necessary definitions in the HyperMesh CFD interface instead. (Aerodynamics and aeroacoustics).

According to the install guide - Chapter 3 - you should just download/install this package
AxhwHyperMeshCFD2025_1_win64.exe
or for Linux
AxhwHyperMeshCFD2025_1_linux64.bin

Is that what you've done? Maybe try re-install?
