I have shared project from database and worked on it. I ran 20+ simulations of different variations and set ups and no problem. Everysingle time i create new run by copying last run and than uploading new 3D.
This time i got strage error. My aircraft has more side-force than lift lift levels are 100% correct. When i checked pressure on fuselage its bigger, far bigger than before and than it should be. So i checked pressure in front of aircraft. In all simulation i got 0 Pa pressure. Now at some distance in front of aircraft there is 175Pa everywhere. And this pressure error creates that sideforce.
Its weird because the pressure in domain is exactly 175Pa but i did not set it up, so why ?
This happens only when simulation version 61_A15_bezocasu_AC.
There are fine results and bad results (bad first and than good ones) … the bad simulation was made by copying good simulation settings …( done this many times and never made problem)
There are slight differences in your BCs between the simulation that is not working as expected and the last simulation. Try re-running it (the latest one) but disable Potential foam initialization. You may need a slightly longer run time however so take note and keep an eye on the result controls.
So i tryed sth. else … i changed a bit mesh settings and generation failed … this appears that there is some error with geometry … but where, i cant find any
