You cannot do it directly with the nodes, but you can do it if you
already have triangulations of the surfaces. Then you can just read
these triangulations from a .msh file, and define a geometry that uses
their associated elementary entity tags to build a volume. There is an
example in "demos/sphere-discrete.geo".
