Dear All,
I am using a geometry imported from CAD and i d like to select a single face and
transform it to get only to work in 2D. Basically i d like to solve it in 2D.
How can i do,
anyone can help?

Hi
there is one way, I believe, but you must decompose your geometry and delete the main part, by using the split down to a surface andor edges and then copy and past it into a new 2D geometry (I cannot test do not have COMSOL accesible just now).
I usually make a dxf, via 2-3 programmes but often the dxf is getting partly corrupted.
Check with V3.5a if you cannot import an IGES, as many CAD software can export just a surface from a 3D into a IGES file, some can even into dxf
But you might also reconstruct it, often quicker.
I know it seems complex, in fact I find it to be too, the "projection" function is missing in COMSOL, but perhaps someone has hooked together a script out there ?
It will be easer in V4 I have heard, something to look forward to
good luck
