oa Numerical Modelling Of Dc Resistivity Problems

Numerical methods for solving the DC geoelectrical problem can<br>be divided into two groups : domain methods and boundary<br>methods. In domain methods the whole of the domain is<br>discretized while in the boundary methods only the boundaries<br>of domains are discretized.Under domain methods one would find<br>amongst others the finite difference method and the finite<br>element method. A popular boundary technique is the boundary<br>element method.
