We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello Alberto, 

this message gets printed when the determinant of Ixx*Iyy*Izz is smaller than the minimum cutoff moments coefficient, which is 1e-20. Even if there were a way to reduce this threshold, these numbers are so small that you risk having a lot of floating point error.

Instead, we would recommend rescaling your problem.
