Is there any Hybrid EM & circuit simulator?

As you all know, EM solvers (FEM,FDTD,MOM)

try to solve PDE (Partial Diff. Equation-- Maxwell Equation).

SPICE like simulators (HSPICE, PSPICE..) are

solveing ODE (Ordinary Differential Equation).

Instead of geting Frequency domain data (S-parameter)

and do macromodeling to export to SPICE, do

people solve them at one shoot?

FDTD can include lumped elements, but

that is not what I am talking about.

I am saying given a system model with

A) lumped networks

B) EM structures

C) Nonlinear devices

can a general solver solve it?

So final challege:

Is there a hybrid Nonlinear PDE & ODE solver/algorithm?

Thanks
