We revisit the accretion-induced collapse (AIC) process, in which a whitedwarf collapses into a neutron star. We are motivated by the persistent radiosource associated with the fast radio burst FRB 121102, which was explained byWaxman as a weak stellar explosion with a small ($\sim 10^{-5}M_{\odot}$)mildly relativistic mass ejection that may be consistent with AIC.Additionally, the interaction of the relatively low ejected mass with apre-collapse wind might be related to fast optical transients. The AIC issimulated with a one-dimensional, Lagrangian, Newtonian hydrodynamic code. Weput an emphasis on accurately treating the equation of state and the nuclearburning, which is required for any study that attempts to accurately simulateAIC. We leave subjects such as neutrino physics and general relativitycorrections for future work. Using an existing initial profile and our owninitial profiles, we find that the ejected mass is $\sim 10^{-2}$ to$10^{-1}M_{\odot}$ over a wide range of parameters, and we construct a simplemodel to explain our results.
