The paper introduces a hypergraph grammar for modeling mesh adaptation in 2D meshes with quadrilateral, pentagon, and hexagonal elements. In this approach, the finite element mesh is represented as a hypergraph, with all mesh transformations defined by hypergraph grammar rules. These rules enable the execution of the h-adaptation of elements, namely the mesh refinement.

摘要

The paper introduces a hypergraph grammar for modeling mesh adaptation in 2D meshes with quadrilateral, pentagon, and hexagonal elements. In this approach, the finite element mesh is represented as a hypergraph, with all mesh transformations defined by hypergraph grammar rules. These rules enable the execution of the h-adaptation of elements, namely the mesh refinement.
