SUMMARY

The discussion centers on the feasibility of calculating a tensor for a system of particles arranged in a spherical shape to derive the radius of that system. The inquiry specifically seeks to understand how to obtain the lengths of the three axes of an ellipsoid by first examining the properties of a sphere. The participants express a need for clarification on the methodology and underlying concepts involved in this tensor calculation.

PREREQUISITES

Can I calculate a tensor of a system( lots of particles) shaped like a sphere, then get exactly the radius of the system?

(I want to get lengths of three axes of ellipsoid, and I'm trying to examine the way with a sphere. )

I’m sorry, but I think it is not at all clear what you are after. Can you perhaps elaborate?
