tyMesher uses openVDB which has no concept of internal or external geometry.
Sounds like an interesting filter I could add to tySelect though....maybe an element selection method based on whether or not a ray cast out of the normal of every vertex hits a face...which would only be true for closed surfaces whose normals are flipped (ie, all the internal geo you're noticing), or geometry inside of other geometry.
