We present a new numerical method for the solution of the forward problem of electrical impedance tomography (EIT) with the shunt model. Given a mesh over the EIT region, we discretize directly the conditions on the current density in equilibrium, and solve the resulting system of linear equations for the amount of current flowing through each side of every element. Afterwards, the distribution of current density and potential are reconstructed. Results of simulations on both 2D and 3D models indicate that the new method gives comparable results to those of the traditional finite element method with linear elements.
