Hi, I would like to generate a 3D mesh consisting of tetrahedrons. I know that using mutlicuboid or multisphere functins, I can do this for a single object, or a collection of similar objects like so:

model = createpde;
gm = multicuboid(2,3,4);
model.Geometry = gm;
generateMesh(model,'GeometricOrder','linear');
pdeplot3D(model)

But what I would like to do is to define a cube, and a sphere inside it, and have the mesh respect the object boundaries. Is this possible? When I tried to append two objects into model.Geometry, it complained saying "Error using pde.EquationModel/set.Geometry (line 49) Assemblies of more than one geometric model are not currently supported."
