3D Stress Invariants Animation from GeoFEST

3D Rendering of the first and second invariants of the stress tensor generated by the GeoFEST Landers Model. GeoFEST is a 3D finite element software modeling solid stress and strain. The data was provided by Dr. Jay Parker of JPL. GeoFEST generated 3D unstructured grid datasets; this particular model contains 1.4 million tetrahedrons and ran for 500 years. The animation displays samples at every five year interval. It first animates the first invariant of the stress tensor variable, then the second invariant represented using two different equations.

The Circulation Pathway of Tropical-Subtropical Exchange

This animation shows the pathway of water at the surface of the eastern equatorial Pacific Ocean. The animation shows the circulation of a specific water mass backword and forward in time for 20 years. The water's distribution is represented by two iso-surfaces (blue and red), illustrating the water's relative concentration. An artifical ocean bottom at 450 m depth and the land are shown in grey color as a visual aid. The simulation was generated by Dr. Ichiro Fukumori of JPL.

Global Ocean Model Simulation

Here are three different variables of the global ocean current simulation from the Climate, Ocean and Sea-Ice Modeling (COSIM) project at Los Alamos National Laboratory: velocity, temperature, and salinity.

Atlantic Ocean Eddy-Resolving Simulation

3D rendering of Atlantic Ocean currents velocity data and Salinity from a 1/6 degree North Atlantic Ocean Eddy-Resolving Ocean Circulation Model by Dr. Yi Chao of JPL. The sequence represents five years of simulated ocean currents, at 3 days per frame (625 frames total).

Thermal Convection Model

3D rendering of thermal convection temperature data from the Thermal Convection Modelling project. This animation is 640x640 and highlights the slice capability of ParVox. During rotation, we are stepping through the timesteps of the dataset, so it is "running" while we rotate the cube.

This is the velocity magnitude of the thermal convection model. It is a volume rendering with the high velocity points being transparent. This helps visualize the current eddies at low velocity.
