Blog #5 in the series The Trillion Cell Grand Challenge, written by Dr. Scott Imlay, Chief Technical Officer at Tecplot, Inc. “Excellence is to do a common thing in an uncommon way.” — Booker T. Washington In previous blogs, I’ve given the motivation for the Trillion Cell Challenge. In this blog I’d like to introduce the details of the challenge and give our results to date. Trillion-cell CFD Dataset At […]
The Trillion Cell Grand Challenge blog #4 by Dr. Scott Imlay, CTO, Tecplot, Inc. Big whorls have little whorls That feed on their velocity, And little whorls have lesser whorls And so on to viscosity. —Lewis F. Richardson This is a famous quote about the nature of turbulence: the energy in turbulence cascades down to smaller and smaller eddies until, at a certain length scale, the turbulence energy can be […]
Blog #3 in the series The Trillion Cell Grand Challenge is about technology trends and the I/O bottleneck. Forecasting is very difficult, especially about the future. —Old Danish Proverb In previous blogs I’ve introduced the Trillion Cell Challenge and given the motivation for why it is a worthy goal. Now I’d like to start discussing the technical obstacles involved in visualizing a solution with one trillion cells. Basic Visualization Pipeline […]
Perform Complex Mathematical Data Transformations Using IF() Statements BELLEVUE, WASHINGTON—January 6, 2015—Tecplot, Inc. announced today that Tecplot 360 2015 Release 1 is now available for general use. Highlights of this release include: Conditional expressions in equations using IF() statements. Triangulation and advanced streamtrace seeding (by customer request). Arbitrary slice improvements to adjust the orientation of arbitrary slices. Improved options for appending data, drag-and-drop, and file dialog performance, especially on networks. […]
in 2030 we should expect the first LES calculations for a large full airplane configuration, and that will require one trillion cells. […]
By Dr. Scott Imlay, Tecplot’s Chief Technical Officer Tecplot’s large-data initiative began several years ago. We’ve spent tens of thousands of developer-hours on removing barriers to large-data visualization: adding parallelization (threading) of performance critical code, optimizing algorithms, and optimizing I/O. Since then, we’ve improved the large-data capabilities of Tecplot 360 dramatically. For example, with Tecplot 360 2014 Release 2, the creation of an iso-surface for a particular one billion cell data set is two […]
As the years go by, more and more engineers and scientists are working with files containing hundreds of millions of cells, with billions on the horizon. Tecplot 360 introduced a new data file format called SZL or subzone loadable (filename extension .szplt) to address the needs of customers who are visualizing large data files, improving interactive performance, and simultaneously reducing memory requirements. When faced with the task of making large […]
Tecplot 360 2014 R2 includes usability and performance features including native Mac support, Fourier transform and extended context toolbar. […]
Using the software for data analysis often requires algorithms with many repeated operations, and in some cases many different operations. Tecplot engineers have created a macro language to streamline these operations. Macros are recordable, easy to edit, and don’t require any development experience. Quick Macro Panel Some commonly used complex and repetitive algorithms (within the aerospace community) have been incorporated into a dynamic Tecplot 360 interface called the Quick Macro […]
Sometimes the biggest challenge of any CFD project is getting your data into the correct file format. This script shows how to create Tecplot format files from MATLAB® data imported from simple text files. […]
