Calculating PSD at a Flux Plane using Flux2PSD.tcl
In Barracuda simulations, the particle size distribution (PSD) of particles crossing a flux plane is often of interest. This post shows how to calculate the PSD when the “Subdivide by…
Analyzing Heat Transfer through Thermal Wall BCs
Thermal Wall BCs in Barracuda allow heat transfer to and from the system, depending on the relative temperatures of the walls and fluid in computational cells. This post discusses how…
MULTIFRAME.tcl
Combining multiple views of simulation results into a single animation is a commonly used technique during post-processing of Barracuda results. The MULTIFRAME.tcl script was written to make this task easier,…
Using Python to Calculate PSDs from Raw Particle Data Files
In Barracuda VR, detailed Particle Size Distribution (PSD) information can be obtained from Raw Particle Data files. There are two ways to generate Raw Particle Data files: When setting up…
Data-mining GMV files using gmv2txt.py
One method of data-mining GMV files is presented in this post. This method relies on converting the GMV files to text format. A warning before we get started: GMV files…
Appending Animation Sequences
In many situations, it is useful to create multiple sequences of animations, and append them end-to-end to create a final long animation. Many of CPFD Software’s marketing animations were created…
I can’t view my results in GMV anymore. What can I do?
There are various reasons that GMV output files (named Gmv.#####) may be unreadable by GMV. The three most common reasons are listed below: 1. Filled hard drive. This is more…
Creating high quality movies
The default animation utility in Linux (xanim) is very convenient for viewing animations. In particular, it lets you step forward and backward through the animation, frame-by-frame, which can be very…
Analyzing data with Python and NumPy
Barracuda can export a large amount of data to text files that can be further analyzed to gain additional insight into the performance of a model. For example, particle snap…
Using cutplanes in GMV
GMV cutplanes are a useful tool for visualizing 3-dimensional simulation results. They allow engineers to get a sense of the 3-dimensional behavior of a system by viewing several planes of…
