Unsteady Data in Tecplot Files

“Big whirls have little whirls That feed on their velocity; And little whirls have lesser whirls, And so on to viscosity.” –Lewis Fry Richardson. Anyone who has watched the flow of water down a river, or the vibration of the control surfaces on the wing of an airplane, knows that fluid flow is generally unsteady (changing over time). In fact, most data, in real life, varies with time. For computational […]

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 […]
