Hi, I'm trying to use es-aero tool for wing analisys. I find impossible to avoid the wing touching the ground;it seems that es-aero make this process automatically but I don't know how to remove this option(if possible),in such a manner to have a mesh sorrounding my model all around. Any suggestion ? Maybe, is es-aero not right for this type of analisys ?

Yes. It is for vehicles not wings.
