/* Thermal Boundary Conditions */
where q<sub>s</sub> is the heat flux passing through the boundary walls.
If q<sub>s</sub> = 0, the Neumann boundary condition is also known as the adiabatic boundary conditionscondition, which represents a perfectly insulated surface:
<math>\frac{\partial T}{\partial n} = 0 </math>
At the interface between the surface of a solid object and air, the convective boundary condition must be enforced:
<math>-k \frac{\partial T}{\partial n} = -h \left[ T(\mathbf{r}) - T_{amb} \right] </math>
where T<sub>amb</sub> is the ambient temperature, and h is coefficient of convective heat transfer having units of W/(m<sub>2</sub>.K).
