Abstract. Personalized simulation for therapy planning in the clinical routine
requires fast and accurate computations. Finite-element (FE) simulations belong
to the most commonly used approaches. Based on medical images the geometry
of the patient's anatomy must be faithfully represented and discretized in a way
to find a reasonable compromise between accuracy and speed. This can be
achieved by adapting the mesh resolution, and by providing well-shaped
elements to improve the convergence of iterative solvers. We present a pipeline
for generating high-quality, adaptive meshes, and show how the framework can
be applied to specific cardiac simulations. Our aim is to analyze the meshing
requirements for applications in electrophysiological modeling of ventricular
tachycardia and electromechanical modeling of Tetralogy of Fallot.
