How to create a regular 3D mesh (tetrahedral or hex-dominant) from a volume in Visual Scripting?

Hi everyone,
I would like to generate a regular 3D volumetric mesh (e.g., tetrahedral or hex-dominant) from a solid body using Visual Scripting. So far, it seems that meshing in Visual Scripting is mostly limited to surfaces.
Is there any way to generate a true volumetric mesh similar to what is available in Structural Model Creation, with control over mesh size and geometric deviation (sag)? 
I’m specifically looking for more predictable and controllable meshing than Voronoi-based structures, which are typically random, irregular, and hard to tune. Due to their stochastic nature, it's often difficult to achieve well-defined mechanical properties with Voronoi meshes.

I would like to achieve something like this:

Any tips, examples, or workarounds would be greatly appreciated! 🙂 

Thanks a lot in advance. 🙂
