Depends what you mean by "at the same time".  If you want to solve a
fully coupled problem, then you can use
ReplicatedMesh::stitch_meshes() to combine them into a single mesh,
and solve the problem on that.  If you want to solve a weakly coupled
problem, then you can create a System on each mesh... either as part
of the same EquationSystems but using subdomain-specific variables, or
as part of two separate EquationSystems, one on each mesh.
