Dear Ivar Kjelberg,
I am a comsol user, recently i am learning to use the "deformed geometry" function in comsol 4.2a,
There is a good example in the model library named "electrochemical polishing".
I don't undstand, in the "Deformed Geometry"-->"Prescribed Mesh Velocity 2" setting,
the "Prescribed y velocity" was setted as "-K*(-ec.nJ)" , the current density "ec.nJ" is normal to the surface,but the velocity in setting only has "y" component. Why?
"normal current density" should match the "normal deformed velocity", not just y component.
I was confused!!!
in "Prescribed Mesh Velocity 2" setting, the coordinate system can be changed from "global coordinate system" to "Boundary System 1 (sys1)", correspondingly, the "Prescribed y velocity" option will be switched to "Prescribed n velocity", it is the right normal velocity. Why comsol didn't do this in the above example for model library?
Looking forward to your reply!
Your help and information is deeply appreciated!!!
Sincerely,
Luyao
