Hello, again ohuli, I would recommend increasing the run time to about 2400s on the simulation because the things like domain and inlets in your convergence plot are not fully balanced out yet, then they will hopefully be close to accurate😁. I believe this is taken into consideration under either pressure or viscous force, but I don’t completely know which one.
here is a conversation about that consideration for lift induced drag - Does Simscale Solve For Induced Drag and Turbulent regions
conclusion - I don’t fully know if it is in viscous or pressure force, but my guess is it is because you probably wouldn’t be able to see the picture of the spiral if it wasn’t for the mathematical model
which I don’t see a reason why it would be in the visualization and not the graph, but to my knowledge, they haven’t added a separate graph line that is only for induced drag which means it is probably under either pressure or viscous, don’t know which one though
(ps. make sure to run the sim a bit longer like described above)]
this has been a cool thing to get me thinking throughout the day,
hope that helps
