Tutorial 5 - Defining Multiple Dispersion Simulations


In addition to being able to quickly add multiple ventilation simulations, in:Flux has capabilities for continually adding dispersion simulations and other project items while calculations are progressing. Users can define multiple inflows (leak sources) and then add dispersion simulations to the scheduler that are made up of any combination of leak sources and ventilation simulations all while other calculations are being performed.


This tutorial will go over adding multiple dispersion simulations to the project by setting up a new inflow and then looking at contours of ventilation simulations to determine re-circulation and low velocity areas in the facility. Commonly, dispersion simulations are run in these low velocity regions to simulate a plausible worst case scenario for the facility - where the gas cloud accumulates around equipment rather than disperses away due to the wind. The accumulation of gas would then be significantly more damaging if the cloud were to be ignited. Simulating these events allows for facilities to be designed so that these larger accumulated gas clouds won't exist or would be detected early so that mitigation measures can be taken.



In this tutorial you will learn how to:

  • Define multiple dispersion simulations for a previously defined inflow

  • View updated monitor point, monitor line, and monitor region data

  • Define new inflows to the project and set-up new dispersion simulations.

  • Make use of contours and vectors to determine re-circulation regions.

  • Define multiple dispersion simulations from varying ventilation and inflow combinations.
