A modified isoparametric mapping fill method to display color mapping of data

摘要

This work presents a reliable and efficient technique for displaying color mapping of data for post-processing of the Hybrid-Trefftz (HT) finite element method (FEM). The isoparametric mapping fill method developed in conventional FE models is generalized to HT FE models. Several steps of the procedure for HT FEM are demonstrated, as well as the aspects to be modified. For illustration purposes, a computer program has been written in VC + + and two 2D examples discretized by HT FEM are provided. The results are found to agree well with the analytical solutions although there are some discrepancies. Finally, conclusions are inferred and extension of this work to the 3D case is discussed.
