In recent years, biomechanical simulation has emerged as a powerful tool in analyzing the performance of human organs—particularly the heart. COMSOL Multiphysics is one of the most advanced platforms for modeling complex physical phenomena, offering a robust environment for simulating the biomechanical behavior of heart under various physiological conditions.

In a typical cardiac biomechanics simulation, the geometric structure of the heart (such as the left ventricle), the mechanical properties of the myocardial tissue, and loading conditions like blood pressure or active contraction are considered.

The geometry of the heart model is extracted based on reputable articles and designed in SolidWorks software, it is available and can be changed.
In this model, we have used Ogden hyperelastic materials for the ventricular muscle.
The fluid is defined according to the characteristics of the blood.
In this model, we have investigated the force created in the muscle and the boundary conditions and initial conditions according to physiological conditions in three cycles.

Key objectives of such simulations include:

• solid mechanics
• fluid flow
• Fluid-Structure Interaction (FSI)
• biomechanics of heart
• Physiologically based boundary conditions
• hyperelastic/ogden
