Nonhomogeneous boundary conditions for the WarpX Ohm solver

[pimanov]

Hi,

I am looking for advice on simulating plasma acceleration devices such as magnetoplasmadynamic thrusters using WarpX. Plasma acceleration is driven by an electric current injected through coaxial electrodes and entering the domain through its boundaries.

A hybrid kinetic model seems appropriate, but imposing electrode-driven current may require nonhomogeneous magnetic field boundary conditions, which I could not find in the current WarpX implementation.

Is this supported for the hybrid solver? If not, what is the recommended way to model current injection in this setup? I would be happy to contribute an implementation if guidance is available.

Do you see any alternative approaches, or know of related work using WarpX for plasma acceleration devices?
