Math Biosci. 2013 Oct;245(2):206-15. doi: 10.1016/j.mbs.2013.07.004. Epub 2013 Jul 12.


The bidomain equations with Neumann boundary stimulation and optimal control of these stimuli are investigated. First an analytical framework for boundary control is provided. Then a parallel finite element based algorithm is devised and its efficiency is demonstrated not only for the direct problem but also for the optimal control problem. The computations realize a model configuration corresponding to optimal boundary defibrillation of a reentry phenomenon by applying current density stimuli.

Keywords: Bidomain model; Defibrillation; Neumann stimulation; Optimal control; Parallel FEM.
