In this paper, firstly we have reviewed the developing of numerical methods used in geophysical electric prospecting, and have listed the current state and developing trend of that, then simply have introduced the main characteristics of ANSYS and also mainly have focused on the steps and key problems of using ANSYS to model numerically DC forward problems; Secondly, based on the differential control equations of voltage potential of point current field, we have introduced the boundary value problem and the variational problem(involved in 2 dimension and 3 dimension); based on secondary development of APDL language raised in ANSYS, we have modeled lots of geophysical models, and we have got same perfect results by analyzing the results of numerical modeling; Lastly, we have achieved the proof that is the ANSYS can be used in geophysical electric modeling with high accuracies. At the end, we have presented the suggestion that ANSYS can be widely used in geophysical forward modeling with valuable applications.
