On: GPU vendor-agnostic fluid dynamics solver in Julia

[samstave]

Cavitation is precisely what I would like to test...

Also, will 'waterlilly' work with a viscosity to Air?

Meaning - toroidal props are a newer entering thing in drones... and I'd like to find out if the above applies equally to fluid/air?

Then you should is a different solver that fills your needs. WaterLily is an incompressible flow solver that works in non-dimensional units (assuming constant unit density). So you can change the viscosity of the fluid by modifying the Reynolds number (with set a set characteristic velocity and length scale).
