hello sir

with all due respect i need some help regarding cross section in comsol multiphysics. i got some problem related to different geometries and cross sections . i tried harder to create trepezoidal form but i failed and didn't got as i want to get . so help to make through this and i have jpg of cross sections .

it's very important plz help me asap

thnx

Hello Sahrukh,
You can create such geometries by using the lofting capability found in the Design Module:

If you do not have a license for the Design Module, please contact your COMSOL representative to request an electronic copy of its documentation. It is quite detailed and includes examples.

thank u so much for helping me , i have made all the cross section of trapezium but i got one problem regarding voltage . how to evaluate voltage of cantilever,which physics i choose to evaluate this potential .

plz help me i stuck in this problem i didn't get potentiona and i m using emi physics.

thnx

I would recommend you start a separate thread for these questions, since they are unrelated to geometries and cross sections.
