Using the Loci-Chem Extract Utility to Create a Tecplot SZL File

By Tecplot’s Chief Technical Officer, Scott Imlay, PhD “In mathematics you don’t understand things. You just get used to them.” — Johann von Neumann I’ve written several blogs on Tecplot’s new SZL technology and how it speeds up the visualization of large CFD data sets by loading only those subzones (small chunks of data) that are needed for the desired visualization. We’ve demonstrated dramatic speed-ups for large data sets. For […]

Working with Unsteady Results

Today’s low-cost computational resources have fundamentally changed the way we approach modern technical challenges. In the world of CFD, one of the most dramatic changes has been the increasing use of unsteady (transient) simulations, which allows engineers and scientists to study moving machinery and turbulence flows more effectively. This article is designed to show you how to work more easily with unsteady results using the improved quantitative capabilities in the […]

We put the “I” back in TecIO

TecIO Read Capability A blog by Dr. Scott Imlay, Tecplot’s Chief Technical Officer “Good things come to those who wait!” – Guinness beer advertisement For many years, TecIO has been a library of utility functions that allow you to output Tecplot binary files directly from your application. There are two versions of TecIO, one for serial output, and one for MPI-based parallel output. The serial-output version can output either classic […]

Tecplot SZL File Output from FUN3D

FUN3D version 13, released in September 2016, supports writing binary files in the new SZL format. I’ve written in previous blogs about the benefits of SZL technology for visualization of large data files. With SZL technology, common visualization tasks are up to two orders of magnitude faster and data files are compressed by up to 50%. This change offers additional benefits to FUN3D/Tecplot users, especially for those running in parallel on […]

NASA’s VULCAN Code Writes Tecplot SZL Format Using TecIO-MPI

In this webinar, you will hear from Dr. Robert Baurle, Research Scientist at NASA Langley Research Center, about his experience implementing the TecIO-MPI library in the VULCAN code. Watch video in MP4 format | View the slide deck in PDF format. VULCAN is a turbulent, non-equilibrium, finite-rate chemical kinetics, Navier-Stokes flow solver for structured, cell-centered, multi-block grids that is maintained and distributed by the Hypersonic Air Breathing Propulsion Branch of […]

Employee Profile: Scott Imlay, Chief Technology Officer

Scott Imlay has a need for speed. As a competitive triathlete, he’s always trying to better his time from the previous race. And as Tecplot’s chief technology officer (CTO), he was the visionary behind SZL, the company’s proprietary technology that allows Tecplot 360 to render images nearly seven times faster than earlier versions of the software. This dramatic performance improvement is the result of faster data load & analysis times, […]

Employee Profile: Dan DeLapp, Vice President of Software Development

Dan DeLapp feels like he has the perfect job in the perfect locale. Although that sounds a bit exaggerated, it’s actually an understatement, according to the life-long Seattle resident who became Tecplot’s head of software development about five years ago. “There is no other place I would rather work than Tecplot. It’s as simple as that,” said Dan, a graduate of the University of Puget Sound. “I’ve been in software […]

Tecplot 2016 Plot-Contest Winners Announced

And the Winners Are . . . Many people like a little friendly competition, as evidenced by the millions of March Madness brackets filled-out at the start of the NCAA’s post-season basketball tournament each year. Those of us here at Tecplot are no different. As a result, we launched our 2016 Plot Contest in January, hoping to receive some stunning images generated by Tecplot software. Based on the submissions we […]

Employee Profile: Raja Olimuthu, Business Development Representative

The saying “timing is everything” has special meaning to Raja Olimuthu. Back in 2009, Raja had the good fortune of working at another company’s trade show booth that just happened to be adjacent to Tecplot’s booth. During the “painfully slow” show, as Raja described it, he struck up a conversation with Tom Chan, who was working at the Tecplot booth. Raja learned that Tecplot was looking to add a sales […]

Employee Profile: Alan Klug, Strategic Account Manager

Technical Knowledge and a Clear Vision Restoring vintage cars is not for the faint-of-heart. It takes technical knowledge coupled with a clear vision of the desired outcome, a dedicated budget, and a good dose of patience. It’s no surprise then that when Tecplot was seeking to fill the newly created role of Strategic Account Manager – a role that would blend advanced technical ability with the demeanor of a customer-focused […]
