Why One Trillion Cells?

Blog #2 in the series The Trillion Cell Grand Challenge, by Dr. Scott Imlay Wind tunnels won’t go away—we’ll need them to store the printouts from our CFD solutions!—Dean Chapman, NASA Ames This is my second-hand memory of a quote attributed to Dean Chapman of NASA Ames as he gave the 1979 AIAA Dryden Lecture1. He was joking, of course, but the lecture was a serious look at the future […]

The Trillion Cell Grand Challenge

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 […]

Converting Your Data Files to Tecplot Subzone Loadable Format

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 […]

Quick Macro Panel Streamlines Repetitive Operations

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 […]
