Hi @r8d8,
yes this is possible, see the sample setup here. For low Reynolds number, surface forces are accurate to within a few %. But my testing so far indicates that at highly turbulent external aerodynamics, absolute forces are off by up to a factor 2 (too large). I'll first need to implement a wall function model to enable more accurate force readings at low-moderate resolution.
However for relative forces or ratios such as lift/drag ratio, it's already quite accurate, and might be useful to for example compare different airframe geometries.
Kind regards, Moritz
Thank you, Moritz Exactly what I need.
First of all, thank you for your efforts, it's a greate piece of engineering. Having general question, before I start digigng deeper: Can one extract macroscopic values as lift and drag from simulation? My intention was to use it for design of a new airframe.
