Not able to select edge in a 2D surface and apply convection boundary condition
I want to define convection boundary condition on the right boundary of the 2D surface. If I select the right boundary with edge select filter, I do not see convection boundary condition option. If I highlight steady state thermal on outline, convection bc appears but I'm not able to select the edge. Instead it selects either face or body. I have attached screenshots of the issue. I'm following Cornell University's course on engineering simulation. I'm not sure where the problem is.
