About the Heart Model

The Heart Model includes the definition of a sequentially coupled electrical-mechanical analysis of a beat cycle with a one-second duration, which corresponds to a heart rate of 60 beats per minute, a typical adult (resting) heart rate.

Introduction

The following sections discuss the Heart Model geometry, material properties, loads, boundary conditions, and analyses definitions. Results presents a series of results, including some that are clinically meaningful. You can use Mechanical Scenario Creation and Physics Results Explorer to examine and modify the model attributes and view additional outputs more relevant to your particular applications. Verification and Validation discusses model verification and validation.

Version Information

The Mechanical Scenario Creation Heart Model has been developed and tested with 3DEXPERIENCE R2018x FP.1814. If you are executing the Heart Model in a 3DEXPERIENCE R2018x Fix Pack release, you must import the 3D XML files for the Heart Model from that same release. The Heart Model is not compatible with any release of 3DEXPERIENCE prior to R2018x FP.1814.
