What is TecIO?
TecIO is Tecplot’s free software library that enables reading & writing of Tecplot file formats (*.plt, *.szplt). We support two distinct APIs that users of the library […]
In Situ Solutions for Analyzing Large Unsteady Fluid Flow
Analyzing large unsteady fluid flows are becoming one of the biggest engineering issues in computational fluid dynamics (CFD). We are working on a solution. […]
Parallel SZL Output from SU2
Parallel SZL output has been implemented directly into the distribution of SU2 using the TecIO-MPI library. This means you need only download and build SU2 and they have SZL file output available. […]
Improving TecIO-MPI’s Parallel Output Performance
The TecIO library is provided to allow third-party applications to read and write Tecplot file format. The library now includes an easier-to-use API for writing SZL files. Its parallel version, TecIO-MPI, enables MPI […]
New TecIO API for Tecplot 360 .szplt Output
TecIO is the library supplied with Tecplot 360 that enables third-party applications to output solution data directly to Tecplot binary-formatted files. […]
Best Practices for Generating Native Tecplot 360 Data Files
If you wish to generate native Tecplot 360 data files automatically from applications such as complex flow solvers, you have a number of options for outputting data into a format compatible with Tecplot. This blog outlines a few “best practices” for doing so. […]
Comparison of Tecplot Data File Formats
Tecplot 360 performance has improved significantly in the last five years, however, the performance experienced by the user varies dramatically with the file format being read. Whenever we tell a developer that a customer is experiencing poor performance, their first question is always “What data format are they reading?”. I’m writing this blog to explain why. […]
Unsteady Data in Tecplot Files
What is the best way to represent unsteady data in Tecplot files? Tecplot divides datasets into zones. These zones may represent different areas of the physical domain, the same physical domain at different time steps, or different results that you may wish to compare. […]
Append Data to Tecplot SZL Files
“Time is an Illusion.” ― Albert Einstein. High fidelity CFD solvers are generally iterative in nature. They move the solution incrementally forward in time (or pseudo time for steady-state solutions) computing each new solution based on the previous solution. CFD engineers often write a snapshot of the solutions at periodic time steps so that they can follow its progress. CFD engineers want to verify that: The boundary conditions are behaving […]
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 […]
