A graph grammar model of the hp adaptive three dimensional finite element method : part II

This paper presents a composite programmable graph grammar model of the three dimensional self-adaptive hp Finite Element Method hp-FEM algorithms. The computational mesh composed of hexahedral finite elements is represented by a composite graph. The operations performed over the mesh are expressed by composite graph grammar productions. The three dimensional model is based on the extension of the two dimensional model for rectangular finite elements. This paper is concluded with numerical examples, presenting the generation of the optimal mesh for simulation of the Step-and-Flash Imprint Lithography SFIL, the modern patterning process
