Has anyone used Air3D or ProSAir to simulate shock wave propagation after TNT explosion? I would like to know your experiences and how easy or difficult it is to simulate with these codes.

I have been looking for codes to simulate TNT shock waves. So far I have tried sonic solvers in openFoam but the results are no where close to those by LSDyna.

Any recommendations are welcome.

Thanks

Meanwhile, I also came across EAGLE-Blast which looks to be promising but not much information available about the code.

If someone has used it, please share your experiences.

It is a fairly easy to use piece of software, but be advised that you will need to obtain a license from Cranfield University and this license is subject to scrutiny and will only be provided to recognised institutions within NATO countries. There is a reason for this and for the limited amount of information available online for these tools. They are blast modeling codes after all. I won't answer any other questions related to ProSAir.

Hi,

The blastFoam solver (https://github.com/synthetik-technologies/blastfoam) was developed and validated for high-explosive detonation and blast wave propagation. It has been validated against experimental testing and simulated results from other CFD codes (e.g. feflo, prosair, lsdyna, etc.).

blastFoam currently supports the following features:

• An arbitrary number of phases/EOS's
• JLW equation of state with constant, linear, and "Miller" afterburn models
• Multiple example and tutorial cases
• Automatic mesh refinement (AMR) support
• Single and multi-point detonation
• High-order (1st, 2nd, 3rd and 4th order in time; 2nd and 3rd order spatial)
• HLLC, AUSM+, Kurganov, Tadmor flux schemes

blastFoam includes the following equations of state:

• Jones Wilkens Lee (JWL) (with afterburn)
• Ideal Gas
• Stiffened Gas
• Cochran-Chan
• Tait
• Van der Waals

By the way, we are offering several free blastFoam workshops at international conferences this year, which will cover how to run blastFoam, theory, etc.:

• May 13: International Conference on Protective Structures (ICPS6), Auburn University, AL, USA (http://www.eng.auburn.edu/icps6/short-courses.html)
  
• June 22-25: OpenFOAM Workshop, Arlington, VA, USA (http://www.cpe.vt.edu/ofw15/)
  
• June 22: Structures under Shock and Impact 2020, Lisbon, Portugal (https://www.wessex.ac.uk/conferences/2020/susi-2020)
  
• Nov 15-20: Military Aspects of Blast and Shock (MABS 26), Wollongong, Australia (https://www.mabs26.com/) [TBC]

I hope this helps!
