Finite element mesh conversion based on regular expressions

The paper presents a method which can convert different types of finite element mesh files to one format. The paper considers only ASCII file representations of the finite element meshes, as this type of representation is usually available for all modeler and simulation software used by engineers. The conversion method is based on regular expressions. The paper also presents a classification of the mesh formats used by several types of engineering softwares.

► Classification of finite element mesh file formats. ► Unified method to convert finite element mesh file. ► Regular expressions are used in the conversion.
