Data assimilation in 2D nonlinear coupled sound and heat flow, using a stabilized explicit finite difference scheme marched backward in time
A stabilized backward-marched explicit finite difference scheme can recover plausible initial data from final-time images in a nonlinear coupled sound and heat flow model, but only for short time horizons.
