Default ICEM: Surface won't follow the curves

Hi guys!

I am a pretty new user of Ansys ICEM CFD but I think I recently did a lot of progress to really dig into that program.

So in the context of a paper for my university I got a 2D-geometry file with a farfield and an airfoil with flap, slat, etc. on it and i wanted to define the farfield as my surface and cut out the airfoil using the command "trim surface". After that I noticed, that the edges of the cut-out-surface just don't follow the curves of the airfoil. Especially at the narrow but dull trailing edges of the components its just a big mess. I firstly thought it would only be a display error but turning on "show full" of the surface didn't solve the problem at all. And on top of it I realised that the mesh I generated afterwards followed evenly the edges of the surface and not the curves of the airfoil.

I hope you know some tricks to fix this problem cause otherwise I'll probably be stuck with that paper at that point.

Many greetings!
