Hybrid finite element method based on novel general solutions for helmholtz-type problems

Fu, Zhuo-Jia; Chen, Wen; Qin, Qing Hua


This paper presents a hybrid finite element model (FEM) with a new type of general solution as interior trial functions, named as HGS-FEM. A variational functional corresponding to the proposed general solution is then constructed for deriving the element stiffness matrix of the proposed element model and the corresponding existence of extremum is verified. Then the assumed intra-element potential field is constructed by a linear combination of novel general solutions at the points on the...[Show more]
