Tecplot Tip: How to insert CAD drawing into 3D flow field data

This Tip describes imposing a 3D wing model on 3D flow field in Tecplot 360. The 3D flow field data are obtained using Volumetric Three-Component Velocimetry (V3V) where the three components of the velocity vectors are measured in a 3D volume of 140X140X100 mm3. Figure 1 shows slices in x-z and y-z planes of the streamwise mean velocity over a periodically cambered plate at an angle of attack of 8 […]

Tecplot Tip: Create an Animation of Slices through a 3D Volumetric Simulation

In Tecplot 360 it’s faster and uses less memory to work with slice zones instead of slice objects. This macro extracts the slice object to a slice zone and synchronizes the dynamic text of a variable with the slice as it moves through the volume. #!MC 1200 # set up variables $!VarSet |TextXPos| = 9 $!VarSet |TextYPos| = 90 $!VarSet |XStart| = 0.1 $!VarSet |XEnd| = 0.9 $!VarSet |XDelta| = […]

Visualization Conference: Trendy Ideas or Priceless Gems?

Last month, I attended the IEEE Visualization Conference in Atlanta. The Vis conference is the premier forum where researchers and academics in the fields of scientific visualization, information visualization, and visual analytics present their latest and greatest ideas. This year Durrell Rittenberg (Vice President of Product Management) joined me on the cross-country trek. I’ve been attending the Vis Conference off-and-on since 2000—it helps me make sure Tecplot is aware of the newest […]

The Egg Came First!

A blog by Tecplot’s Chief Technical Officer, Scott Imlay. Lately I’ve been struggling with the visualization version of the classic causality dilemma, and I finally have an answer! But first, a little background. As many of you know, we have been working hard on a new technology called subzone load-on-demand (SZL) that minimizes the amount of data loaded by Tecplot 360. The basic idea is to divide a large dataset […]

Post-Processing One Billion Cells

By Dr. Durrell Rittenberg, Vice President of Product Management Over the last decade, I have followed several technological advancements in numerical simulation post-processing. While there were improvements in the area of parallel rendering and client-server technology, these approaches were limited to those with large computational resources. The most notable breakthroughs available to most engineers came in the form of improved graphics cards – thanks in large part to the gaming […]

Best Picture Award in Physical Science

Long time Tecplot customer, Frank Muldoon, and his colleague, Hendrick Kuhlman, at the Vienna University of Technology, received the “Best Picture in Physical Science award” for this image of Invariant Streamtubes of a Hydrothermal Wave in a Thermocapillary Liquid Bridge. Congratulations to you both! Abstract In microgravity, large-size cylindrical liquid bridges can be established, because they do not break. Differential heating of the support disks creates a thermocapillary flow which is […]

From Atoms to Airplanes

The Materials Genome Initiative Just over two years ago, President Obama announced the Materials Genome Initiative. The name is sort of silly—materials don’t have genes—but the ideas behind the initiative are significant. In short, the goal is to “discover, develop, manufacture, and deploy advanced materials at twice the speed that is possible today”. To do this, we must develop a wide range of analytical techniques that will allow materials to […]
