I understand that making incompressible fluids allows one to get approximations by removing the pressure variable, which simplifies the calculations. This makes sense for most liquids where they are relatively incompressible, but this doesn't work for gaseous fluids. Is there another way to approximate these calculations with some simpler function for pressure. I assume that having some flat repel between close particles would be pretty close to how gases would behave under pressure laws for a naive simulation.
