Transient Heat Conduction

We need to add back in the time derivative to do a Transient calculation...

$$$$\rho cp \frac{\partial T}{\partial t} - \nabla \cdot k \nabla T = 0$$$$

This term already exists in the HeatConduction module it's called HeatConductionTimeDerivative...

All we need to do is use it in an input file...

Now to switch up the outlet BC...
