Attractors in Millipede

Hi everyone, I'm trying to extract from Millipede analysis some numeric values in determined points (found from the maximum stress or bending moment values) in order to use them as modifiers-attractors.

I'm trying to achieve something like this: as the stress value increases, the attraction in that point must be higher.

I'm not sure about using Millipede for this goal: do you know any other plug-in to suggest me?

I'm attaching two images to clear what I mean.

Thanks everyone!

Andrea
