A User Interface for Fluid Dynamics Code

Senior Project: 1993-1994

NIST scientists have developed an object-oriented (C++) software library for the numerical modeling of fluid dynamics applications with associated heat- and mass-transfer. This code is used in various chemical engineering models, including electrodeposition and corrosion studies, and the chemistry and flow inside a chemical vapor deposition (CVD) reactor. Data is input to the program to define the physical parameters of a given simulation, the geometry of the domain and its breakdown into finite elements, and the user's choices of exactly what forms of the transport equations to solve and what boundary conditions to use to define the numerical problems. The goal of this project was to develop a graphical user interface for this system. The interface allows the user to select appropriate equations, choose specific terms to be included or excluded, and select boundary conditions, physical parameters, and other attributes of the model to be simulated. The output of the user interface is an input file in the format required by the modeling software. The project was developed using an object-oriented design with implementation in C++. The graphical user interface was developed using Interviews and the X Window System on an HP9000-720 workstation.
