The Adaptive Hierarchical High Order Element

Jiang Kexun; Wen Daigang (Chongqing University)  
The adaptive hierarchical high order element is one of the high order finite elements. It is proposed specially for the p and h-p version adaptive computation ofFEM.In this paper, the main featltres of the hierarchical element are disc ussed indetail,and itS comparison with ordinary high order elements (i, e. the lagrange typeof element)is made for 2- D and 3- D electrostatic problems, The computed resultsshow that the two kinds of element have the same accuracy, though their shapefunctions are greatlly different.
