摘要

摘要提出了一种新的并行数值框架CarNum,用于计算心脏机电等多物理问题中数学模型的有效耦合。该框架基于开源项目,这些项目提供了平台的核心功能。计算心脏机电学需要一个复杂的管道来求解不同类型的常微分方程和偏微分方程。我们的框架允许实现不同的数值方案,并在多物理耦合中提供更多的控制。本文概述了新平台的概念以及心脏生物力学数值建模的细节。用著名的心脏机电基准进行的首次实验显示,与其他组的实验结果一致,并具有良好的并行可扩展性。

CarNum: parallel numerical framework for computational cardiac electromechanics
Abstract A new parallel numerical framework CarNum is presented for efficient coupling of mathematical models in multiphysics problems such as computational cardiac electromechanics. This framework is based on open source projects, which provide the core functionality of the platform. Computational cardiac electromechanics requires a complex pipeline of solving different types of ordinary and partial differential equations. Our framework allows one to implement different numerical schemes and provides more control in multiphysics coupling. This paper outlines a concept of the new platform and details of numerical modelling of cardiac electromechanics. First experiments with well-known cardiac electromechanics benchmarks show good agreement with other groups and decent parallel scalability.
