VISUALIZATION

Scientific visualization has always been a critical component of the development of the computational materials science of concrete models. The initial version of the CEMHYD3D model (circa 1989) was developed on a PIXAR imaging computer in the NIST laboratories (the same PIXAR² that has gone on to create such famous animation movies as Toy Story and A Bug’s Life). Using this machine, the "hydration" could be viewed interactively, greatly expediting algorithm development and debugging activities. This ability to visualize results is crucial for complex models, as models always produce some results, no matter if they are right or wrong. Visualizing results can quickly show if the results obtained are ridiculous, and once the results are correct, visualization helps one to understand the physical significance of large and complex streams of data.
