The isomer yield ratios of ${}^{184}\mathrm{Re}$ in the incomplete fusion of the ${}^9\mathrm{Be}+{}^{181}\mathrm{Ta}$ system were measured at energies around the Coulomb barrier, using online activation followed by offline $\gamma$-ray spectroscopy method. The platypus code that is based on a classical dynamical model is employed to analyze the measurements. By applying a phenomenological approach, model calculation managed to fairly reproduce the order of magnitude of the yield ratios at above barrier energies. Through the study, it is shown that the platypus code in conjunction with a phenomenological analysis can provide a reasonable explanation of isomer yield ratios resulted from incomplete fusion of weakly bound projectiles.
