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,…
Installing Extra Packages for Cygwin
The default Cygwin installation included with Barracuda VR includes a minimal set of packages to support the operation of GMV on Windows. For some tasks, it is necessary to install…

Setting particle-to-wall interaction parameters
Particle-to-wall interaction parameters are specified in the Barracuda Virtual Reactor GUI on the Particles window. The values of these three parameters – normal-to-wall momentum retention, tangent-to-wall momentum retention, and diffuse bounce – can have…
Does Heat from Chemical Reactions Go to the Gas Phase or the Particle Phase?
When chemical reactions are being modelled in the Barracuda Virtual Reactor, it is sometimes important to consider and control where the heat from reactions goes. This post discusses the distribution…
