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 algo-rithm. 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.关键词
