NegativeArraySizeException

Hello everyone,

I am working on simulating the plume of a SPT-100 and for this I define the energy distribution as an 2D energy-angle matrix:

SPIS_error_negativeArraySize_2
SPIS_error_negativeArraySize_1

However, when running the simulation the following message prompts in the console:

SPIS_error_negativeArraySize_3

Running the 2D energy-angle matrix of the generic thruster model works. I tried a finer and coarser resolution as well as changing the energy range but unsuccessful.

Has someone experienced this negative array size exception and knows how to avoid it?

Cheers,
Zoe
