Quasi-periodic or harmonic oscillation transforms into fundamental oscillation as external force increases in forced van der Pol oscillator. Numerical analyses reveal that quasi-periodic or harmonic oscillation can exist metastably in a finite time interval even in a region where fundamental oscillation is stable, which has not been predicted theoretically.
