Dear experts of Comsol and Moderators.
I have a question.
I design ICP chamber and get the data of EM fields. Normals...
Actually 3D data scale shows like En=250V/m, Hn=130A/m, but when I do Cutline and check 1D datas,
It shows like 12000 V/m and 300A/m, and also shows not reasonable Peeks. When I see 3D graph, it is pretty Uniform, so i couldn't understand what are those peeks, and where are those big digits from?
Dear Professionals please answer my questions.
Thank you for your kindness!
P.S. Sorry I can't attach some picture or model, because confidential information and company policy.
Thank you!

Hi
often its worth to make a neuitral simple model and try to reproduce the effects with that for exchange and learning purpouse.
Have you cheked the mesh density and if your pits and digs are mesh related ?. (tuen on wireframe and no interpolation
Often in EM you get quite strong singularities, particularly at sharp corners, edges, that is often worth to "soften" by fillets

Good luck
