The broad band spectra of two Swift/BAT AGNs obtained from Suzaku follow-upobservations are studied: NGC 612 and NGC 3081. Fitting with standard models,we find that both sources show similar spectra characterized by a heavyabsorption with $N_{\rm{H}} \simeq 10^{24} \ \rm{cm}^{-2}$, the fraction ofscattered light is $f_{\rm{scat}} = 0.5-0.8%$, and the solid angle of thereflection component is $\Omega/2\pi = 0.4-1.1$. To investigate the geometry ofthe torus, we apply numerical spectral models utilizing Monte Carlo simulationsby Ikeda et al. (2009) to the Suzaku spectra. We find our data are wellexplained by this torus model, which has four geometrical parameters. The fitresults suggest that NGC 612 has the torus half opening-angle of $\simeq60^{\circ}-70^{\circ}$ and is observed from a nearly edge-on angle with a smallamount of scattering gas, while NGC 3081 has a very small opening angle $\simeq15^\circ$ and is observed on a face-on geometry, more like the deeply buried"new type" AGNs found by Ueda et al. (2007). We demonstrate the potential powerof direct application of such numerical simulations to the high quality broadband spectra to unveil the inner structure of AGNs.
