These are two volumetric mesh generator libraries. See details on their websites: [Cleaver2](https://sciinstitute.github.io/cleaver.pages), [TetGen](http://www.tetgen.org/). I would recommend Cleaver2, as it is more robust, has better support for multi-material meshes, and has free, non-restrictive license.
