We present modeling and analysis of the ejecta of nova V723 Cas based onspatially resolved IR spectroscopic data from Keck-OSIRIS, with LGSAO (adaptiveoptics module). The 3D photoionization models include the shell geometry takenfrom the observations and an anisotropic radiation field, composed by aspherical central source and an accretion disk. Our simulations indicaterevised abundances $log(N_{Al}/N_{H})=-5.4$, $log(N_{Ca}/N_{H})=-6.4$ and$log(N_{Si}/N_{H})=-4.7$ in the shell. The total ejected mass was found as$M_{shell}=1.1\times 10^{-5}$ $M_{\odot}$ and the central source temperatureand luminosity are $T=280,000$ $K$ and $L=10^{38}$ $erg/s$. The 3D models arecompared to basic 1D simulations to demonstrate the importance of using morerealistic treatments, stressing the differences in the shell mass, abundancesand characterization of the central source. The possibility of V723 Cas being aneon nova and the puzzling central source features found are discussed.
