• in:Flux CFD Software Passive Opening Capability

in:Flux v3.0 Release Highlights

in:Flux Feature improvements:

Version 3.0 is a major update to the in:Flux solver, to improve its capabilities for the wide range of applications for which it is now being used. The improvements particularly affect internal flows (indoor ventilation) and transient releases.

Passive inlets and outlets can be set for indoor ventilation simulations.
Monitor Regions now show minimum, maximum and average values in the monitor region for all variables. This can […]

in:Flux v2.14 Release Highlights

in:Flux Feature improvements:

User-defined transient inflow profiles can now be used created for multiple variables, including upstream pressure and temperature (high pressure leaks), and velocity, flow rate, power and temperature (custom emissions, shown above).
Added HCO reactions for fire simulations (alongside the standard hydrocarbon CxHy type reactions) for fuels of type CxHyOz:
Added the ability to define user-reactions, including user-reactions for non-DIPPR® fluids. This provides a great deal of flexibility […]

  • Jet Fire CFD Simulation Fire Modeling Incident Radiation Contour

in:Flux v2.0 Release Highlights

We are proud to announce the launch of Fire Modeling with in:Flux
Over the past two years, we have been developing the fire modeling capabilities of in:Flux, and today, we are pleased to launch this capability to all our customers.

To run Fire CFD simulations:

Right-click on “Fire Simulations” and select “Add Fire Simulation”
Choose the inflow and wind condition, just as you would for a Dispersion Simulation. Both steady-state and transient […]

  • influx wind rose

in:Flux v1.42 Release Highlights

in:Flux Feature improvements:

More options for assigning consequence values to dispersion simulations in the Risk Manager.
Ventilation-only risk projects are now better handled in the Risk Manager.
Wind Rose in the Risk Manager now shows “Site North” to clarify the orientation of the wind.
The option to copy leaks has been added to most property editors in the Leak Frequencies tab in the Risk Manager.
More refined meshing options […]

  • inFlux v1.41 Release Highlights - Custom Gas Cloud Sizes

in:Flux v1.41 Release Highlights

in:Flux Feature improvements:

Custom gas clouds can now be created in the Gas Cloud Analysis window. This allows for reporting of gas cloud volumes other than the standard gas clouds included in the software.

As an example, the Flammable Gas Volume Fraction > 10% LFL can now be defined. Other ranges can also be defined by the user such as 10 < % LFL < 50
These custom gas clouds […]

  • inFlux v1.39 Release Highlights - Flammable Gas Volume Fraction

in:Flux v1.39 Release Highlights

in:Flux Feature improvements:

New “Flammable Gas Volume Fraction, %LFL” post-processing variable which shows the flammable concentration and can be used to compare multiple cases even when those cases use different flammable gases.

As an example, if you have only one simulation with one inflow of Methane then the Flammable Gas Volume Fraction, %LFL would be the same as the Methane Volume Fraction. However, if the simulation has one inflow of […]

  • Insight Numerics Online User Guide Front Page

in:Flux v1.35 Release Highlights

in:Flux Feature improvements:

User guide, tutorials and other resources have been linked to http://help.insightnumerics.com. This has been done to speed up workflow and to make it easier for our users to review and learn features of the software. We anticipate adding more tutorials throughout 2020 as well as walk through youtube videos.
Improved meshing for leaks located close to the ground, within the boundary layer. In previous versions, the mesh […]

  • inFlux v1.34 Release Highlights - Helideck Turbulence

in:Flux v1.34 Release Highlights

in:Flux Feature improvements:

Helideck turbulence modeling capability for CAP437 studies has been added to in:Flux.

To use the Reynolds Stress turbulence model (RSTM) for your project, open the “Advanced” box when adding an External Ventilation Simulation and select “Helideck Turbulence” under “Purpose”.
A helicopter icon will appear next to simulations using this turbulence model.
Upon completion, a new variable will be available for post-processing: Vertical Fluctuation Velocities, m/s. This is […]
