Hi to everybody
I’m developing a 3D lid driven cavity case with D3Q19 model and BGK approximation. I’ve got some problems with the code, in particular I don’t understand where I have to apply the streaming and the collision step, that’s to say in the inner core of the domain (bulk fluid) or also on all nodes of the domain (fluid+walls+corners+edges).
Can someone help me? Thanks for your answers!
