Open Boundary
This node adds a boundary condition for modeling heat flux across an open boundary; the heat can flow out of the domain or into the domain with a specified exterior temperature. Use this node to limit a modeling domain that extends in an open fashion.
Open Boundary
Enter the exterior Temperature T0 outside the open boundary.
