Abstract: We present an object-oriented finite element software package which employs XML and design patterns in order to solve a problem which is fundamental to the simulation of viscoelastic flows. The XML format increases flexibility in data handling, while design patterns provide a high-level organizational structure. The application problem and the finite element methodology are described, along with the opportunities presented for incorporation of the software tools. Numerical experiments comparing results with and without XML and design patterns are also presented.
