Changing Chemistry on Restart
The chemical reactions and rate equations solved by Barracuda VR can be changed on restart. However, the GUI currently does not support this advanced restart feature. This post describes how…
Setting Executable Permissions for Scripts
When running a script in Linux or Cygwin, it is necessary to give the script executable permissions. This post shows how to set the permissions so a script can run.…
Understanding the PATH Environment Variable
Operating systems use the PATH environment variable to find programs. The PATH environment variable stores a list of directories in which the operating system will search for programs. Most of…
Calculating PSD at a Flux Plane using flux2psd
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 “Bin by…
