Ok references updates after rebase, can you approve again @andiwand ?

I should be able to supply an input file if you don't want to run Pythia locally.

I faintly remember @FabianKlimpel implemented boundary surface checking by using all boundary surfaces and then ordering them in the most likely sequence, in order to be able to try all...

Looking at the log, it seems the propagation does in fact reach the target boundary surface that it was trying to get to: ``` 16:20:56 Simulation VERBOSE Consider boundary surface...

@asalzburger suggests to check if this happens during truth tracking as well, or only combinatorial finding of real seeds.

Thanks first of all. I don't think the magnetic field interpolation should fail silently in this way, to be honest. If the particle propagation goes out of bounds of the...

While the InterpolatedBField indeed has under and overflow values, we had issues in the past where it went out of bounds and we didn't notice and only after non-negligible debugging...

Got it, it's here https://github.com/acts-project/acts/issues/784 and then I introduced this error mode in https://github.com/acts-project/acts/pull/825. I also had some discussion with @HadrienG2 about this in https://github.com/acts-project/acts/issues/821. One technical issue is that...
