| Abstract: | Based on the differential control equations of voltage potential of the point current field, we introduce the boundary value. The special commercial FEM program named ANSYS has been successfully adopted to this problem. Based on secondary development of APDL language in ANSYS, we have made calculations on lots of 2.5D geophysical models, and got same perfect results of numerical modeling. We prove that the ANSYS can be used in geophysical modelling with high accuracies and valuable applications. |
