Bug when using different morphology and a transform sphere cut

[shahmeerbaweja92]

Describe the bug

I am trying to reproduce an RVE with a centered, small spherical void inside it using cubic morphology instead of using 'voronoi', and then later mesh with c3d8 (hex) elements.

$ neper -T -n from_morpho -transform "cut(sphere(0.5,0.5,0.5,0.106))" -morpho "cube(7)" -format tess -o mgvoidsmall_cube
