Isogeometric Analysis of the electrophysiology in the human heart: Numerical simulation of the bidomain equations on the atria

摘要: Abstract We consider Isogeometric Analysis (IGA) for the numerical solution of electrophysiology atria, which in this work is modeled by means bidomain equations on thin surfaces. First, we coupled with Roger–McCulloch ionic model simple slabs. Here, our goal to evaluate effects spatial discretization IGA and use different B-spline basis functions accuracy approximation, particular regarding front velocity dispersion error. Specifically, high polynomial degree , p global order continuity C − 1 computational domain: results show that such beneficial accurate approximation solution. Then, a realistic application Courtemanche–Ramirez–Nattel two human are represented NURBS
