        Thermo-electric calculations solver without the optical part.
    
        This solver performs under-threshold thermo-electrical computations.
        It computes electric current flow and temperature distribution in a self-
        consistent loop until desired convergence is reached.
    
        The computations can be executed using `compute` method, after which
        the results may be save to the HDF5 file with `save` or presented visually
        using ``plot_...`` methods. If ``save`` parameter of the :meth:`compute` method
        is *True* the fields are saved automatically after the computations.

        either the launch time or the identifier of a batch job if a batch system
        (like SLURM, OpenPBS, or SGE) is used.
