This study establishes a standardized software benchmark for cardiac elastodynamics to ensure reproducibility and consensus in cardiovascular mechanics simulations across different computational solvers.

Limitations

  • Increased discrepancy in the biventricular case compared to the monoventricular case
  • Dependency of the solution on the discretization space and fiber orientation

Abstract

In cardiovascular mechanics, reaching consensus in simulation results within a physiologically relevant range of parameters is essential for reproducibility purposes. Although currently available benchmarks contain some of the features that cardiac mechanics models typically include, some important modeling aspects are missing. Therefore, we propose a new set of cardiac benchmark problems and solutions for assessing passive and active material behavior, viscous effects, and pericardial boundary condition. The problems proposed include simplified analytical fiber definitions and active stress models on a monoventricular and biventricular domains, allowing straightforward testing and validation with already developed solvers.
