Help connecting objects together

[John-MF]

Hi, I am trying to connect together two objects with different mesh size where one is smaller than the resolution of the other.
I can easily fix one point of one object to one point of the other with BilateralLagrangianConstraint, but I would like my object to not just move based on one point of the other's mesh, but be influenced by the surrounding body as if it was really inside it.

For example here I have a small MechanicalObject in red, fixed to a point of the blue object, and that I would like to be connected by to the surrounding points too.

I feel like it should be possible to find a proper mapping between the two objects, but couldn't find how to not just end up with points fixed to the same position.

I would love it if anyone had tips on how to face this problem

Hi @John-MF

Indeed, I think what you are looking for is a BarycentricMapping between your red and blue representations.
Let me know if you need any more insight (if so, please share a basic scene example that you already have)

Cheers
