Hello everybody !

I'm running a simulation of flow around a ship with a k-omega SST turbulent model.
I have an inlet, an outlet, four symmetry planes and a hull.

I did the simulation with first order schemes for divergence, linear schemes for gradschemes and interpolation schemes, linearCorrected for laplacian and corrected for snGradSchemes. It worked and I obtained coherent results for the velocity, pressure, and forces on the hull.

I'd like now to run it with second order schemes but I really don't know which one to choose because I tried some of them (linearUpwind, linearLimited, skewCorrected linear) on a previous simulation with an other hull and no one worked.

Do you have some advice? is there a advisable second order scheme for this type of simulation? Is there an other scheme (grad, interpolation) I must change?

thanks a lot for any advice !
