The Application of COMSOL Multiphysics in Direct Current Method Forward Modeling

With point electric source as example, this paper describes direct current method forward modeling with COMSOL Multiphysics. By comparing and analyzing COMSOL Multiphysics modeling results and theoretic values of typical models, the validity and feasibility of direct current method forward modeling based on COMSOL Multiphysics is proved. Due to the powerful mesh dissection, solution function and abundant post process operation, it shows an important significance of applying COMSOL Multiphysics in geophysical modeling.
