Incompressible Solver - What does this mean?

Hello,
I am wondering what the effect of an incompressible solver is? So I have a mass flow inlet and a pressure outlet. If I switch to an incompressible solver, the density of my ideal gas does no longer depend on pressure. But what happens to my ideal gas formulation: p = rho *R *T According to: https://www.sharcnet.ca/Software/Flu...ug/node332.htm my density is now calculated by an operating pressure. 1) So for each cell in my domain the navier-stokes equations are solved for velocity and pressure. But for calculating density, not the local pressure of the cell is used but the operating one in p = rho *R *T ? 2) But why can I avoid this way osciallations regarding my solution (for example air velocity). Thank you for your explenations Best regards Moritz |
