Hello,
I'm calculating an airfoil with an angle of attack. When the Momentum is switched to First Order, the drag coefficient has the value of 0.01094. When I switch the Momentum to Second Order the drag coefficient has the value of 0.01756. Does anyone has an idea,why there is such a great difference? |

Results from 1st order are not acceptable, but this does not mean results of 2nd order are validated automatically.
