How to define line of symmetry, ie above and below are mirror images

Please login with a confirmed email address before reporting spam

Hello

I have a cylinder with some stuff placed in it on the x-axis and want to calculate the stress in the caused by the difference in thermal expansion.

I want to use the symmetry of the x-axis but I dont get how to do this. I've found this page www.comsol.com/support/knowledgebase/1038/ describing roughly how to do it but I dont understand the last part where I choose '"Symmetry", "Insulation" or similar'.

Does someone know how to specify the line along the x-asis as a line of symmetry?

In the thermal stress package I have the options of:
Pairs>Symmetry or
Pairs>Continuity

If I choose Symmetry I cant select annything... what to doo?

Unfortunately not... I just solved the whole thing instead (didn't take too long)
