Forward problem solution of EMSIs using BEM with isoparametric cubic elements

Numerical solution of the potential and magnetic fields for a given electrical source distribution in the human brain is an essential part of the electro-magnetic source imaging. In this study, a Boundary Element Method (BEM) is used that employs 10-noded cubic triangular elements. The results are given in comparison with the solutions obtained using linear and quadratic elements. The relative difference measure obtained for the numerical models that use different element types show the superiority of quadratic and cubic element types.
