SPIS 6.1.0 Thruster Distributions Bug

Hey.

I was just wondering if anyone else has experienced this bug when defining their source.

When running SPIS 6.1.0 with given input data for a thruster distribution, in this case, Fittable Maxwellian Source, the software abruptly stops in the “Initializing numerical kernel” phase. I think there is some kind of issue where the data is not saved properly since the software displays “null at” for some properties.

Any ideas?
