Introduction of Research
Computational Science 1/4

In our heart simulator, the virtual cells, myocardium, blood and torso are all modeled using the finite element method (FEM). The FEM is a numerical method used to solve field problems described by partial differential equations. The figure on the left shows the heart model, in which the myocardium and blood domains are divided into about a million finite elements. Zooming in on a part of this model shows the finite element mesh of the middle figure, and further zooming shows the tetrahedral elements. Although each finite element can only represent a simple field, this is sufficient because a complex field can be divided into many simple fields. In our heart simulator, voxel elements and tetrahedral elements are used to analyze the electrical phenomenon and mechanical phenomenon, respectively.
