The Sun undergoes various oscillations through which we can probe deep into its convective interior. Inertial modes are slow rhythms or low-frequency oscillations restored by the Coriolis force. They have recently been observed in the Sun. There have been several attempts to model the inertial modes employing several simplifying assumptions. In this work, we use Dedalus, a flexible spectral code, to compute the eigenmodes of the Sun in the inertial frequency range. This framework helps us to examine the sensitivity of the modes to different model setups, including incompressible, anelastic, and fully compressible ones. In this talk, I shall present two main findings: the assumption of incompressibility is unjustified, and the inertial modes weakly couple with the radiative interior.
