Restarting a Simulation from the Command Line
Restarting a simulation from the command-line can be useful when GUI access is not available, or when writing scripts that run the Barracuda solver. This post describes the steps necessary to…
Adding “Current Directory” to the Linux PATH
Adding the current directory, also known as “.”, to your Linux systems PATH environment variable can make executing scripts more convenient. However, there are some security issues to consider as…
Enhanced steam methane reforming simulation by means of the computational particle fluid dynamics (CPFD) method
The ability to massively reduce the runtime of Barracuda Virtual Reactor simulations through the use of a GPU is highlighted in this paper regarding the modelling of a Steam Methane Reforming (SMR) looping process.
Analysis of Particle Behavior inside the Classifier of a Raymond Bowl Mill While Co-Milling Woody Biomass with Coal
Researchers from BYU utilized CPFD to present a novel analysis of woody biomass and coal particle mixing inside a classifier.
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…
