[comsol 3.5a]Extrusion coupling variables

Please login with a confirmed email address before reporting spam

Hello
I have the same 3D geometry in two different geometry space, geom1 and geom2.
In geom1 I launch a radiation (heat transfer) analysis, with this analysis i find T distribution i particular on one surface.
Now I want to assign this T distribution obtained along one interesting boundary in the corrisponding boundary in geom2 to launch a conduction analysis.
I have tried to use Extrusion coupling variables with linear transformation (source and destination are the same surfaces only in different geom) and launch the 2 analysis at the same time but in conduction analysis I don't find the T distribution that i try to assign with extrusion variables.
Thank you in advance
Luca

Hello Luca,

please check following thread:

There is an excellent description of how to use coupling variables there, given by Ivar Kjelberg
