Capvidia joins the SIMULIA “Living Heart Project”

24 October 2014

Capvidia joins the SIMULIA “Living Heart Project” to contribute with the CFD simulation.

The Living Heart project has been initialized by SIMULIA Dassault Systems (http://www.3ds.com/products-services/simulia/solutions/life-sciences/the-living-heart-project) involves a consortium of companies, cardiovascular researchers, educators, leading software developers, medical device manufacturers, regulatory agencies, and practicing cardiologists in order to achieve a realistic simulation of 3D human heart model.

 

The FE model created in this project is the second generation with increased accuracy to mimic the electrical, mechanical and flow behaviors of a complete human heart. Hence, this multidisciplinary model should help to increase the understanding and to better combat cardiovascular problems. The emphasis is to open new frontiers in diagnosing, treating and preventing heart diseases.

Creating a realistic model of a beating heart, we desire that one day the medical professionals shall be able to diagnose and treat patients based on the computer simulation results. These models can serve as core technology base for education and training, medical device design, testing and regulatory processes thereby creating a path for rapidly translating cutting edge innovations into improved patient care.

Capvidia´s contribution to this project is the CFD simulation part. While Abaqus launches the FE based electrical and mechanical simulation, our FlowVision simulates the blood flow behavior through the heart. The heart deflections and the flow are calculated with the co-simulation engine (MPM-Multi Physics Manager) linking SIMULIA Abaqus solver with FlowVison solver; this leads to achieve the full fluid-structure-interaction (bi-directional coupling). By studying the flow characteristics at different critical locations (e.g. level of turbulence around the heart valves), blood shear stresses and pressure distribution one can better understand the heart conditions and reactions to external triggers.

The FlowVision operates directly on the FEM geometry calculated in SIMULIA Abaqus, thereby ensuring highest level of realism in the simulation. This is just the very beginning of this project and we shall deliver more interesting and enhanced information in the near future as the work is progressing and the FE model is being further improved.
