If Navier-Stokes equations are unsolvable how does CFD software calculate simulation?
The equations solved for the most of the CFD software are the Navier-Stokes equations (let's stay in the general case of compressible ones). … The most of the CFD software still solve the equations numerically. Even if the well posedness is not verified, it is still possible to solve the equations. …

How are panel codes like xfoil able to model turbulence and predict drag?
The answer is in the resolution of the boundary layer by solving integral equation, for which a potential solution is needed (see this answer). XFoil uses Thwaites method coupled with Michel method. I …

Effect of Vortex Shedding in lift and drag coefficient?
The steady state solver consider that the solution should converge to a steady state. Let's consider for example (and for simplicity) to be in a finite volume solver. What the algorithm is trying to d …
