A High-Order Coupled Finite Element/Boundary Element Human Torso Model
The problem considered is that of trying to determine the potential distribution inside a human torso as a result of the heart’s electrical activity. Due to the material properties of the biological tissues involved and the relatively slow frequency of the heart’s cycle, the governing equation to be solved for the potential in the torso outside the heart is the generalised Laplace equation
where ∅ is the potential and a is the conductivity tensor.
$$ \nabla .(\sigma \,\nabla \phi ) = 0 $$
