Feature : "Configurable" massdensity

[Hisnio]

Hello,

I was wondering if it was possible to have the massdensity of 'AdaptiveBeamForceFieldAndMass' be a matrix instead of a float as it is already the case for the YoungModulus of 'BeamInterpolation'.
Indeed, I am modelizing a beam with different material along the way and, thus, different Young Modulus and mass density but I can only modify the former.

I was also wondering if it was possible to have the same feature for the geometric parameters of BeamInterpolation i.e. being able to define different radius between two beams.

Kind Regards
