Hello all,

I would like to model the interaction between an arbitrary shape(defined by a gts file) and a flexible rod. I am using gridNodes and gridConnections to model the flexible rod. I thought I could use pFacets to model the arbitrary shape. However, I found that this pfacet body is hollow. Moreover, when I scale the size of this shape (lets say its a cube and I scale the side length by 2), its mass is not scaling as expected (I expect the cube mass to increase 8 times, but I got 2). I thought I could use polyhedron [1], but I did not find an Ig2 functor for polyhedra and gridConnection. Do you know how to model a shape that is capable of interacting with a gridConnection?

kind regards,
Rohit John
