On a second read, I would like to rewrite your workflow as follows:

I would prefer to be able to:

[x] buy a GPU, -> [v] Download SimReady USD of your GPU from nVidia website.

[v] whip up some CAD

[v] import USD of nVidia card into CAD

[v] measure the geometry using CAD

[v] Design cooling element

-> Export CAD to USD

-> Import CAD as SimReady Asset into nVidia Omniverse with tests you need.

-> Once simulation is OK send final CAD to production (or better from GPU simulation into simulation of production on one of the factories or 3d printers)

In this scenario:

- SimReady USD of a GPU must already exist inside nVidia. They could make it available for simulation inside Omniverse. (or build open high level model yourself)

- Thermal simulation app is something that nVidia needs for their business now and in the future. They could share current software with public and let people like you download it, change it and run simulations with your changes (or build open high level model yourself)

I'm wondering how difficult it would be to simulate important effects on your models. Do you think the above process has potential to improve your process or did I miss some important detail of your work?

Oh, with regards to the actual design, I DIY my own computational engineering software, based on implicit modeling which works well for theses sorts of complex geometries. I don’t know about the simulation, I guess I theory i could export the model into a sim. I would base the broad strokes of the design known working reference implementations. I think there is a ton of potential in custom vapor chamber stuff so maybe I’ll play with that but I think it’ll easily become overkill. I think perhaps have the vapor chamber printed and thermal glue skived heatsinks on top. Unlike normal GPU designs I can tolerate much more noise for air pressure.

For me, good enough is good enough I’m not going to be super optimized as the cost tradeoffs for such optimizations don’t work out as favorable at my scale.
