Yes it is compatible with newton.
notice that that tool is no enough, you still nee to get a 3d bolleean library.
the are at many oft them, I just type 3d Boolean in google and click the first link.
http://www.finalmesh.com/boolean3d.htmso what you do is you take your solid mesh and you running thought the Boolean library,
that will produce the hollow mesh.
the hollow mesh is made of all king of pylyhedrums.
so you take that mesh and convert it to the HACD formal and convert to a collection of convex shapes.
then you take the collection of convex shaped and you build the Newton compound.
another option is that maybe these tools or some form of them are build in blender.
so you might be able to export the set of convex shapes to a file and just read it and make the newton compound.
note: I just saw that the Boolean is commercial, but there are many other who are free and very good, just look for 3d Boolean
