Getting 2-D geometry from 3D object

Please login with a confirmed email address before reporting spam

Hello,
I am running a mode propagation analysis of a waveguide so need to run a set of 2-D mode solvers along the propagation direction. I am wondering is it possible to get 2-D gemetry of the 3-D waveguide cross-section in comsol automatically? I have gone through almost everything in the helpfile and it seems usually comsol use 2-D to build 3-D geom but not the other way around.

I would greatly appreciate your answers.
regards,
Max

Hi

Unfortunately, no, from my knowledge, and I'm missing badly that functionality too.

What you can do is to define a 2D workplane for a 3D volume and then you get the projection shadow lines, but you need to overwrite/paint your geometry over the shadow lines. Your "pick" magnet points are still given via the projected cut geometry, so COMSOL has 90% of the info to create the intersection, but it does not finalise the 3D to 2D projection functionality, unfortunately, and so far ...

Good luck

Thanks for reply. I will do that in solidworks then.
