Abstract: We present results of comprehensive seismic modelling of the B-typemain-sequence pulsator $u$ Eridani, which consists in parallel fitting of thepulsational frequencies and corresponding values of the complex, nonadiabaticparameter $f$, defined by the bolometric flux perturbation. This kind ofstudies, which we call {\it complex asteroseismology}, provides a unique testof stellar opacities. Our results indicate a preference for the OPAL data.
