Visualizing a three dimensional hydrodynamic model

A three-dimensional finite-element hydrodynamic model was constructed to simulate tidal cycles in Galveston Bay over a one-year period in order to view changes in water velocities and salinity. A project undertaken to visualize the simulation results is reported. The project comprised analyzing model requirements and determining suitable visualization techniques, visualizing a preliminary, smaller-scale model to verify the techniques; and visualizing the full-scale model. Problems encountered and resolutions of problems at each stage are described. Validation, as well as insights revealed about the model through the preliminary and final visualization, are discussed. Current application of visualization techniques to the model is reported
