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…
How to generate animations in batch mode
Note: This post assumes two things: GMV attribute files have been generated and You are using GMV 4.5.7 or newer on Linux. BATCHMOVIE.sh is a script, bundled with recent Barracuda…
Can I specify a heat flux at a thermal wall instead of a temperature?
Currently the only option for thermal walls is to specify a temperature. This is has a nice physical basis, as the temperature gradient is the driving force for heat transfer. …
Why do I get mass balance errors for my chemical reactions?
We frequently see questions similar to the following: “I’m sure that the stoichiometry of the reaction I’ve entered is correct but I continue to get a mass balance error. What…
Why is my new license not shown on the RLM status page?
The RLM status page shows active licenses only. To view the RLM status page, open a web browser and point it to <license_server_hostname>:5054, where <license_server_hostname> is the hostname or IP…
Why is the contact friction model off by default?
Before discussing default settings, let’s first consider the motivation behind the contact friction model. The Eulerian/Lagrangian formulation of the fluid/particle flow equations used by Barracuda is what allows it to…
Non-zero K-factor use at pressure boundaries
The use of a K-factor adjustment results in an additional pressure drop across a pressure Boundary Condition (BC) as a function of fluid flow. Using a non-zero K-factor value can…
Can Barracuda simulate non-Newtonian fluids?
The CPFD methodology used in Barracuda solves both the fluid transport equations and the particle transport equations. The viscous terms in the fluid momentum equation utilize a Newtonian formulation -…
Fluid bed characterization using Electrical Capacitance Volume Tomography (ECVT), compared to CPFD Software’s Barracuda
Four models created using Barracuda Virtual Rector are compared with results from an Electrical Capacitance Volume Tomography (ECVT) sensor and from high speed pressure measurements.
