Significant Deviations between First Order and Second Order
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.
