        Takes ``micromagneticmodel.System`` and drives it in the phase space.
        If ``append=True`` and the system director already exists, drive will
        be appended to that directory. Otherwise, an exception will be raised.
        To save a specific value during an OOMMF run ``Schedule...`` line can
        be passed using ``compute``. To specify the way OOMMF is run, an
        ``oommfc.oommf.OOMMFRunner`` can be passed using ``runner``.
