Heart models and meshes are used in computational simulations of cardiovascular surgeries and cardiac arrhythmias. There are numerous challenges in generating high-quality meshes of cardiac anatomies; these are due to the complex geometry of the heart, its high curvature, and its motion. In this talk, we present our method for generation of high-order curvilinear tetrahedral meshes and apply our method to the generation of high-quality, high-order meshes of the 3D myocardium geometry.
