I'm simulating the motion of a solid body and i'm able to do when the volume of the object is about the order of 2e-07 m3, now i'm trying to do with a rescaled model, with volume of 2e-08, and consequently lower values of the inertia tensor, is there any way to handle such type of situations? I'm already using the cgs unit system which gives the highest numerical values for the inertia but are of order 1e-05 each and maybe is too low ?

Many thanks in advance
