With this kind of simulation, I mean the Lagrangian-like one, do you still have a mesh or you have to solve the equation for every particle, like you do for every nodes in the grid?

This method (SPH) is meshless. Conservation equations are solved on the particles themselves.
@ what about the cpu and ram? I've been thinking of upgrading my pc for learning some cfd but am not entirely too sure what components bring the most value for it

@@christianaranas5981 , this model is an exception because it runs on the GPU. Instead, most models require multi-core processors and usually lots of RAM. For commercial simulation, I have two workstations each with 2x Xeon 4214 processors and 96 Gb of RAM. But of course, you don't need as much if you just want to start learning. Probably 16~32 Gb of RAM and an i7 or ryzen 7 would suffice.
Hello
How did you generate the boundary conditions?
And the boundary layer in the buffer layer ?

What specs are the system you used to render this on?
This one was run and rendered on my day-to-day PC, which has a GTX 1660 Super.
