    A method of numerical branching is proposed for piecewise-smooth steady-state problems when any analytical expressions
    are not known for the regions of smoothness of the function involved. The performance of the method is shown for model
    bifurcations in discretised contact problems with Coulomb friction. First, different parameter settings in its input are
    tested so that the optimum one can be proposed. Then, the method is used to investigate the behaviour of the bifurcations
    for different meshes. All solution branches seem to be discovered reliably if the parameters are set up properly.
