I can verify that 187.3 s into the simulation, for no apparent reason, increases massively. I will take a look into this.

Try running with a very small time step. Because the target flux is an explicit solution, the model can it too large a time step in rare instances and lose a good solution.

Your values for the "Human" target do not seem correct. I can't provide you with correct values but you should check them. I would also strongly suggest you use a much thicker target. I am assuming you are interested in the impact of the heat on a living being and people are not 0.1 mm thick and that extra thickness has impacts even on the surface. It definitely can have an impact on the numerics in CFAST.

This seems to run fine in CFAST 7.7.4. There was a bit of confirmation bias on my part. At 180 s into the simulation the upper layer in the compartment is 150 C and increasing. FED is not calibrated after 1 since that is when the heat, in this case, is deadly. I am going to close this and if there are any other problems please go to the discussion or start a new issue.
