  We revisit the accretion-induced collapse (AIC) process, in which a white
dwarf collapses into a neutron star. We are motivated by the persistent radio
source associated with the fast radio burst FRB 121102, which was explained by
Waxman 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 a
pre-collapse wind might be related to fast optical transients. The AIC is
simulated with a one-dimensional, Lagrangian, Newtonian hydrodynamic code. We
put an emphasis on accurately treating the equation of state and the nuclear
burning, which is required for any study that attempts to accurately simulate
AIC. We leave subjects such as neutrino physics and general relativity
corrections for future work. Using an existing initial profile and our own
initial 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 simple
model to explain our results.
