Voxel-based finite element modeling

Hy everybody!
I’m only a beginner in segmentation and meshing models and I have one precise question: how can I create voxel-based FE model.
I’ve already read some articles dedicated to this topic (GitHub - lassoan/SlicerSegmentMesher: Create volumetric mesh from segmentation using Cleaver2 or TetGen; Generate a voxel-based mesh; Image to Finite Element Mesh: An End to End Workflow) but haven’t found some algorithm how to do it.
I need to create bone-cartilage model according to its density (based on Housefield units) and to get multi-colored mesh.
In older article, there is an algorithm of how to do it using IA-FEMesh extension, but in current version of 3D-Slicer this extension isn’t available. I’ve installed two extensions designed for my purpose (CleaverTetMesher and SegmentMesher). I can create only one-colored mesh using these tools, but I need multi-colored (like at picture).
Can anyone explain me how to do it or give some links for tutorials.
Thanks in advance!!
