Hi,
With the updated simulator release I am seeing issues with the solution.  I have attached all the relevant files.

When I run the simulation with a time dependent heat source (ie., 20*(t<300e-6)) the solution does not look right.  See the screen shot of the output (Screenshot_Single_Step.png)

So I split the solution into 2 steps: first step has a fixed heat source (ie., 20) for tmax = 300e-6 and use the output as the initial condition for the second step that has a heat source set to 0 for tmax = 0.01.  The output (Screenshot_Two_Step.png) from this looks as what I would expect.  

So it looks like the time dependent heatsource is not set properly in the simulation.

Can you kindly look at this issue.

Thanks.
