Advanced Analysis announces the release of exploCFD7   27-04-2020


04-27-2020 exploCFD7 Released.


Advanced Analysis announces the release of exploCFD7. The new release significantly expands the explosion case modelling  capability of exploCFD to include new several new features. The software features  the world's most detailed capability to model BLEVE (Boiling Liquid Expanding Vapour Explosion)  cases which are a potentially catastrophic category of explosions of great concern  to a large number of  Major Hazard Facility Operators as well as some storage facilities.


A BLEVE occurs when pressurised liquid in a vessel is suddenly released into an environment at a P-T point above its boiling P-T curve. The release is due to the failure of the vessel brought on by very high  temperature loads for example from a jet fire impinging on the vessel or a large pool fire which attacks the structural integrity of the vessel.  


The new version of the software also has dust cloud explosion modellng which is also a high consequence category of events   and explosive charge modelling capabilities which are capable of modelling high energy explosives such as Ammonium Nitrate and IEDs.


Revolutionary New CFD Tool

  • Revolutionary consequence analysis tool for  explosion modelling and one of the easiest to use

  • Reads in a plot plan and recognises its features to construct the geometry. No geometry construction necessary 

  • Models Gas explosions BLEVE Dust Explosions and Explosive charges as well as high explosives such as TNT or AN

  • Continuous development based on expert consultants feedback

  • Worldwide technical support and training


In order to make the appropriate decisions for a facility with major or significant explosion hazards, you need accurate quantification of overpressure magnitudes and distributions which are not afforded by crude 1D radial models. exploCFD enables you to accurately assess explosion hazards rapidly and accurately.



Benefits of exploCFD for explosion analysis

  • Extensively validated models with over 3500 cases with realistic geometries.  

  • Easy to use, rapid problem setup using plot plan PDF 

  • No need for time consuming geometry build from scratch. 

  • More accurate than 1D models, easier to set up

  • Assess diverse hazards - assess a wide range of flammable and toxic hazards

  • User friendly - intuitive GUI and easy to access results.
