NX Thermal Symmetric Model

I have  a model that has symmetry, so I only meshed half of it. When I look at the nodal results I am seeing as I get to the edge of the symmtery that there is a small decrease in temperature. But when I run a full model where I have a 360 degree mesh I do not have this small decrease in temperature. Could this simply be a post processing issue?

Do you apply symmetry boundary condition like zero thermal flux?

In a thermal model, a face with no boundary conditions *is* a symmetric face. In the absence of a boundary condition, a free face will have no flux in the normal direction. There are no "symmetric" boundary conditions to be applied.

Contacted MAYA and was told to utilize the Radiation Periodicity option. Doing that solved the issue.
