   Oceananigans is used for climate modelling and they use a different set of equations for this purpose (hydrostatic Boussinesq equations instead of Navier-Stokes equations). On the other hand, the numerical method both use is the same, finit

   There is no explicit LES model, aka implicit LES. All the additional dissipation required when running coarse meshes relies on the numerical dissipation of the implemented schemes.

   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 Reyn

   You are right. Ideally we would like to keep everything in GPU memory of course. But we have not been able to render CuArrays with Makie yet, and I'm not sure if that is actually implemented, as you suggest. If so, it would be great to

   Cavitation has nothing special other than multi-phase flow. And implementing a VOF method is definitely in our roadmap. You can currently simulate it without cavitation to get a feeling of the unsteady flow solution, or wait for us to imple

   As long as you can define a signed distance function, and the function governing the motion of the propeller, WaterLily can simulate it!
