Seg3D does not create geometry. You would have to take the segmentation
and run it through a program to convert it into a finite model. This
can be as simple as dicing the data into tiny cubes to more
sophisticated methods such as finding reasonable boundary surfaces
between the various materials and making a best-fit of tetrahedra or
hexagons to that geometry with as few elements as possible.
I believe SCI has released software to convert segmentations into
tetrahedral meshes. One of the others may be able to help with that.
Otherwise you'll be off to google or the COMSOL community to see how
they are creating their meshes from data.
