I am very well aware of this. I told everyone, that perform this correct is imposible, but my boss knew better. My company get old KWS (electrical box for mines) and they wanted doing simulation explosive in AnSys, then perform real research through specialist and compare results. I know that results will be diffrent, but I have to perform duties receive from boss. If I had to do for real use, I would refuse. It is cool, that you give a such advise, however I was realised of this. Thank you very very much for help.
