Force free fields can be generalised to Trkal flows in magnetohydrodynamics if a special velocity field parallel to the magnetic field is introduced. Such flows decay exponentially in time if a constant viscosity and a constant resistivity are added. The stability of generalised Trkal flows is investigated and a sufficient condition for non-linear stability is derived. For low velocities, this condition reduces essentially to a non-linear sufficient stability condition for force free fields.
