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

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. […]

Appending Data to Tecplot Files

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 […]
