Thanks a lot Fillia! I can select the faces now. One more minor question - I am trying to adjust the lift direction (l_x and l_y) for different AoA to define the lift coefficient. However, they don’t exactly add up to 1 due to numerical errors (we get long decimals after sine and cosine), and SimScale doesn’t allow this
How do SimScalers usually define their l_x and l_y to define the direction of lift?
Hi there, a workaround would be to set them as 1 according to your original coordinate system, and after the simulation you can manually calculate the vectors according to your angle, does this make sense?
I was looking for another way, but that works too! Thanks much for the support (new to SimScale and impressed by the firm support here )
I am happy to hear that, feel free to reach out anytime
Ok but that is my question. How to align the lift and drag direction to the angle of attack in the result controle, as I see it I can only choose between x y or z direction for the lift and drag direction, and as I understand it that is the global x y z direction of the cad model not the flow direction at a specific angle of attack.
Have a look at the solution here, cheers!
