Using the two-phase flow model in the IPARS simulator and 64 nodes of the IBM SP2 at Pacific Northwest National Laboratory, Center for Subsurface Modeling researchers examined the behavior of a million-grid-block reservoir with four injection and twelve production wells. The displacement front advancing from the injection wells is clearly seen in the upper contour plot, with the variation in water saturation at the bottom of the reservoir projected onto the plane below. This plane also shows the computational mesh, which is refined in both horizontal directions around each well, and the irregular boundary of the reservoir.

Our Computational Visualization Center, collaborates with Earth Simulator Center (Dr. Tetsuya Sato), Yokohama, Japan for extremely large the datasets (22GB). Their transient oceanographic dataset consists of 5 variables: temperature, salinity, U, V, W (velocity) and 4 timesteps spread over 3days.
