Starting from a contact Hamiltonian description of Lìenard systems, we
introduce a new family of explicit geometric integrators for these nonlinear
dynamical systems. Focusing on the paradigmatic example of the van der Pol
oscillator, we demonstrate that these integrators are particularly stable and
preserve the qualitative features of the dynamics, even for relatively large
values of the time step and in the stiff regime.
