4. Setup (Physics)

Adiabatic Boundaries

The top and left sides of the rectangular domain are perfectly insulated. In order to incorporate these boundary conditions, first (Right Click) Steady-State Thermal > Insert > Perfectly Insulated, as shown below.

Next, hold down Control and click on the top and left sides of the rectangle. The purpose of holding down Control is that it allows you to select multiple items. Then, (Click) Apply in the "Details of Heat Flow" table.

Isothermal Boundary

The bottom side of the rectangular domain has a constant temperature of theta=1. To implement this boundary condition, (Right Click) Steady-State Thermal > Insert > Temperature , as shown below.
