I would like to know how to find out how long it takes for a steady state thermal model to reach a steady state solution. I mean the theoretical time it would take for the model to reach equilibrium, not the time it took for the CPU to process the solution.
E.g. The metal bar heats up to a final temperature of 100degC after 4 minutes 2 seconds. At the moment my solution only tells me that the metal bar heats up to 100degC.

Steady State Thermal is the solution after all changes over time have stopped and the system is in its final equilibrium state.
Transient Thermal allows you to take a thermal model with defined initial conditions, for example the body starts at 22 degC, and some boundary conditions such as all faces exposed to a fluid at 100 degC and solve the temperature as a function of time.

Ok that's great; I'll give it a go. Is there a way to copy the load conditions which I have assigned to a steady state thermal analysis to a transient analysis which is using the same geometry. This would prevent me from having to reassign all the same load conditions again.

Yes, in Workbench, just right mouse click on Steady State Thermal and Replace with Transient Thermal. All the assignments already made should remain undisturbed. You will just have to define an initial time step and an end time.
