Abstract In this paper, secondary field algorithm was used to study CSAMT two-dimensional forward problem. Forward modeling used finite-element method, and it employs compressed storage and conjugate gradient technique to accelerate the speed of forward algorithm. In addition, topography was added to the forward algorithm. Finally, the algorithm was tested by means of a synthetic model. The test shows promising results.
