Modeling complex biological systems in computational life sciences requires specialized tools that can perform medical-image-data-based simulations and can handle complex and realistic anatomical models. The required solvers must be optimized for modeling living tissue and high-performance-computing-enabled to cope with the frequently large numerical problems. A multi-physics platform that satisfies these requirements has been implemented and used to investigate a wide variety of relevant applications, some of which are presented in this paper. The simulation platform consists of detailed, parameterized anatomical models, a segmentation and meshing tool, a wide range of solvers and optimizers, a framework for the rapid development of specialized and parallelized finite element method solvers, a toolkit-based visualization engine, a PYTHON scripting interface for customized applications, a coupling framework, and more.

The scientific impact of this study can be summarized as:

  • A multi-physics simulation platform has been developed that can be employed to support device development and optimization, safety assessment, basic research, and treatment planning.
  • The platform includes novel, high-performance-computing-enhanced solvers optimized for modeling living tissue.
  • The platform has been applied to relevant topics such as hyperthermia cancer treatment planning, tumor growth modeling, evaluation of the magneto-haemodynamic effect as a biomarker, and physics-based morphing of anatomical models.
  • The platform offers a flexible, powerful environment in which to perform realistic simulations of physical, physiological, and biological effects in living tissue and complex anatomies.
