RLC circuit by isopotential
===========================
This example shows how to use the corresponding ``contype`` in the
``connect_isopotential()`` method to define an RLC circuit as an
inlet boundary condition. The executable file for LS-DYNA is
``ls-dyna_smp_d_R13.1_138-g8429c8a10f_winx64_ifort190.exe``.
