Problem with timewarp and AddThermalFlux

[wizzlebippi]

I've been having a problem with AddThermalFlux and timewarp in a mod I'm working on. Basically, in exchange for constant heat output, the part constantly produces power. At 100x tmewarp, it's perfectly happy for extended periods of time. If I increase timewarp to 1000x, my test ship immediately overheats and occasionally exploads despite being equipped with sufficient radiators. Here's the line of code:

this.part.AddThermalFlux(Heat * TimeWarp.fixedDeltaTime)

Thermal simulation is done differently above 100x time warp. The easiest way to not make things explode would be to prevent your part functioning above that threshold

That's disappointing, but understandable from an optimization standpoint. Do you (or anyone) have any insight as to how thermal simulation works beyond 100x, or a way to prevent the ship from immediately cooling off at 1000x?

Analytic mode does the following:

1. Sum up all the fluxes on the vessel (i.e. all internal fluxes, all solar/body radiative fluxes)

2. Calculate a resting temperature based on what would be required to radiate out at that same wattage.

Analytic is essentially a "fast forward" button for thermo: it asks "what would be [a simplification of] the final state the vessel will acquire, in thermodynamic balance with its environemt". However, there's an interface you can use especially for this situation: it will tell your partmodule to slow down when the vessel starts overheating.
