Same Simulation Different Model, but result numbers that make no sense


So, if I am understanding this the solver uses a super basic CFD code to get a very rough solution, and then takes that solution and plugs it into the “master” (for a lack of better term) solver, in hopes of increasing the rate of convergence?

If I was doing a simpler solution (say a rear or front wing only), it would probably help? However due to how complex the flow is around this car, the potential flow actually hurts the convergence?


Hi @mmccann,

Yes, that is crudely the process, I wouldn’t say that it would work better for a less complex problem, there is just some case that it doesn’t help, but usually this is the more complex cases.

Good luck,
