“The work they did isolates the steady parameters from the craziness of unsteady flow.”

a movie,” notes Mike Peery, president of TecPlot, Inc. unsteady flow can be compared to looking at a static image vs. However, after five years of research, a team of scientists from MIT, San Diego State University, and United Technologies has developed a breakthrough methodology that allows engineers to precisely determine the location and angle of flow separation in both 2D and 3D as well as steady and unsteady flow conditions. One of the more important yet difficult calculations to understand is the precise behavior of the breakaway of fluid from walls. Whether the domain is material stress or fluid flow, any data is only as good as the engineer’s ability to interpret and apply it. In any simulation, obtaining accurate results is only half the battle. Breuer, Department of Fluid Mechanics, Helmut-Schmidt University Hamburg. Tecplot Chorus is a simulation analytics framework that unites physics visualization with data management and analytics in a single environment.Ĭurrently, one Tecplot Chorus license is available to use on Pleiades or NAS-supported desktop systems.Figure 1: CFD Results of Flow Separation Behind a Cylinder. TIP: If you are having problems running Tecplot through VNC, you can try running it with the -mesa option, which uses software rendering. The NAS Tecplot 360 license does not restrict the number of instances of Tecplot 360 that can be run concurrently.

Interactively exploring data through cut planes (slices through a region), iso-surfaces (3D maps of concentrations), particle paths (dropping an object in the "fluid" and watching where it goes).

Estimating the order of accuracy of solutions.

Normalizing data deriving flow field functions (such as pressure coefficient or vorticity magnitude).

Calculating grid quantities (such as aspect ratios, skewness, orthogonality, and stretch factors).

Common tasks associated with post-processing analysis of flow solvers (for example, Fluent, STAR-CD, OpenFOAM) include: Tecplot 360 is a computational fluid dynamics and numerical simulation visualization software program used for post-processing simulation results. Two Tecplot products are available on NAS systems: Tecplot 360 and Tecplot Chorus.
