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.
