Set reflective boundary condition for pin by pin hexagonal problem

Hi everyone,

I have a pin by pin (ONLY have 7 pins in total) hexagonal benchmark problem, the outer boundary conditon is reflective. My question is how to set boundary condition for this problem?

Thanks a lot. Sorry to post this question again.


@jerrylizy You would need to set the boundary condition for each of the planar surfaces that compose the outer boundary to be reflective.
