@jousefm, @1318980: I guess we have kind of ‘stop ship’ bug here for CFD simulations. In mean time, perhaps a banner can be put on SimScale project front page, saying: “Please discard your drag values for a moment, they are not correct. However, while waiting for a fix, you can try to use only 50% of it”.
All credits for spotting the culprit of miscalculation of drag should go to @DaleKramer.
Cheers,
