Abstract:Since the drawing precision of the classical computer graphic techniques is not enough to suit the post-processing of the finite element method, an improved visual scheme is proposed based on the interpolation mechanism of isoparametric elements, mainly including algorithms of the hidden surface removal, nephogram and isograms. And the related codes in VC ++ are also developed. Having been implemented in local elemental coordinate system instead of in the global coordinate, the new modified visual algorithms of nephogram and isograms are proved to be much easier and better approaches for the post-processing of every kinematic and mechanical characteristic in finite element model, such as displacement and stress, which improve the drawing precision of the classical method and have high computational efficiency.
