  • VizCraft: A Problem Solving Environment for Configuration Design of High Speed Civil Transport
    Goel, A.; Baker, Chuck A.; Shaffer, Clifford A.; Grossman, Bernard M.; Mason, William H.; Watson, Layne T.; Haftka, Raphael T. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1999-09-01)
    We describe a problem solving environment (PSE) named VizCraft that aids aircraft designers during the conceptual design stage. At this stage,an aircraft design is defined by a vector of 10-30 parameters. The goal is to find a vector that minimizes a performance-based objective function while meeting a series of constraints. VizCraft integrates the simulation code that evaluates a design with visualization for analyzing a design individually or in contrast to other designs. VizCraft allows the designer to easily switch between the view of a design in the form of a parameter set, and a visualization of the corresponding aircraft geometry. The user can easily see which, if any, constraints are violated. VizCraft also allows the user to view a database of designs using parallel coordinates.

  • WBCSim: A Prototype Problem Solving Environment for Wood-Based Composites Simulations
    Goel, A.; Phanouriou, Constantinos; Kamke, Frederick A.; Ribbens, Calvin J.; Shaffer, Clifford A.; Watson, Layne T. (Department of Computer Science, Virginia Polytechnic Institute & State University, 1998-12-01)
    This paper describes a computing environment named WBCSim that is intended to increase the productivity of wood scientists conducting research on wood-based composite materials. WBCSim integrates Fortran 77-based simulation codes with a graphical front end, an optimization tool, and a visualization tool. WBCSim serves as a prototype for the design, construction, and evaluation of larger scale problem solving (computing) environments. Several different wood-based composite material simulations are supported. A detailed description of the prototype's software architecture and a typical scenario of use are presented. The system converts output from the simulations to the Virtual Reality Modeling Language (VRML) for visualizing simulation results.
