Testing chemistry in a single cell model
CPFD Software generally recommends testing chemical reactions and rates in a single-cell model before implementing in a full scale model. What do we mean by a single-cell chemistry test? There…

How does Barracuda VR handle distributor plates or spargers?
This open-ended question comes up a lot. There are multiple approaches that could be used, depending on the purpose of the simulation. This post explores several options for modeling fluidization…
Known Issues 16.0.1
Barracuda VR 16.0.1 Issues affecting this version: KI-1: Particle Drag is not calculated for pure liquid particles when simulation has no solid materials KI-2: 2D data is missing output conversion…
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…
What gas species should I initialize in my unit?
For a system with a mixture of reacting gases, the user has a decision whether to initialize the system with an inert gas (frequently, nitrogen), which will be displaced upon…

How to use Interact features from a script or the command line
If you’re interested in automatically controlling BCs based on user-specified parameters, please see the newer post: Using a PID Controller Script to Control Boundary Conditions Example Scenario Your model has a thermal…
What are appropriate cell aspect ratios?
The cell aspect ratio is the ratio of the longest to shortest side in a cell. A perfectly cubic cell would have an aspect ratio of 1, while a rod-shaped…
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…
How to track number of computational particles over time
In Barracuda simulations, it can be useful to track the number of computational particles present in the system over time. This can give users one indication of whether the particle…
