A novel model of 3D 12_node infinite element is presented in this paper.The mapping functions in the novel model are clear_cut in the concept and concise in the form.The problems,which emerge in using the infinite element model of the reference, appear in using the novel model.A comparison between the novel model and the infinite element model of the reference is made by computing the examples.The results show that the novel model has the advantages in performance and accuracy.
