From driving galactic chemical evolution to creating compact objects, core-collapse supernovae (CCSNe) act as unique laboratories that influence many areas of astrophysics. With the advent of gravitational wave (GW) astronomy, astronomers stand poised to detect GWs that encode information originating from the heart of a supernova, regions inaccessible with electromagnetic observations. This talk reviews results from high-fidelity CCSN simulations, connecting the expected GWs produced in core-collapse events to the internal supernova physics.  It presents a novel method used to constrain the progenitor, as well as potentially predict explosion properties. Likewise, it outlines recent numerical developments in the FLASH multiphysics code that improve the predictive power of numerical models for supernova multimessenger signals.
