On the detection of artifacts in Harmonic Balance solutions of nonlinear oscillators

•Addition of an error criterion allows the detection of artificial solutions.•Classification of solutions in large relative error, low relative error stable and low relative error unstable ones.•Application to nonlinear oscillators showing varieties of multiple solutions. Harmonic Balance is a very...
