Brochures and pricing information for your mcrash software?

Post by MSI » Tue Jul 23, 2019 10:55 am

Q: (via email) I was interested in some brochures and pricing information for your mcrash software?

A: We do not market the mcrash program. We wrote a couple research papers with the intent of possibly marketing mcrash But then technology made msmac3D so fast (and it includes damage AND trajectory simulation) we saw no point to spend the time and effort to create a marketable version of mcrash.
We are in the process of implementing components of mcrash into the automatic iteration/optimization option of msmac3D (see SMAC2003 - The Automatic Iteration of SMAC)

CRASH was created as a simple pre-processor for SMAC. However due to the simplicity of the technique (and the cost of running SMAC on mainframe computers back in the 70s-80s), and the fact it was to be used only for statistical purposes looking at trends, NHTSA opted to use CRASH (they have subsequently created WinSmash which is a NHTSA USE ONLY version of CRASH (NHTSA got tired of litigation related subpoenas, etc for CRASH))

Fast forward 40 years and many folks use and/or teach CRASH as a primary reconstruction program in litigation (and of course if all you have is damage it is good, and it is a good first pass technique)

Q: (followup email) I have read your paper “A Revised Damage Analysis Procedurefor the Crash Computer Program”. Has that algorithm, or something similar, been incorporated into your software? I do a lot of low speed work and am very aware of the shortcomings of the original CRASH algorithm for computing delta-v’s is low speed accidents.

A: Unfortunately no we haven't. With the wonderful reception that paper received from some folks at SAE (we published 4 SAE papers that year and all made SAE transactions, but this one they chose to attack)...
  • Some CRASH coefficients cottage industry types played protect and so worked their best to trash or dismiss the paper...hoping we'd pull publication of the paper…for documentation of our joyride see the 1997 SAE Review Process.
We had other projects so figured we'd focus on other matters since why waste time on it anymore?
It was finally recognized by SAE for the quality paper it was but for us it was too little too late
It made 1997 SAE transactions and the 2008 collection CRASH Reconstruction Research: 20 Years of Progress, but the damage was done to our spirits on the topic and so we lost interest in implementing it as a commercial product.
  • To add insult to injury, in 2001 an author improperly tried to attack it in a SAE paper in which the author tried to implement our suggested modifications. He did so incorrectly and never once tried contacting us for assistance and to insure the veracity of the implementation...it was a sloppy paper which simply included an incorrect implementation to try to trash the ideas from our 1997 paper.
We switched gears and have had fun playing with msmac3D automatic iteration/optimization and other projects.
Definitely need to put that CRASH damage analysis update back on the front burner since essential especially for low speed collisions.

Currently Ray and I are working to implement a test in the msmac3D automatic iteration/optimization(video) to calculate crash damage analysis type deltaVs to compare them with SMAC results to help guide the iteration while also checking/testing that the CRASH coefficients used/selected are compatible.
  • What many folks sometime forget is when cars crash the crush is a system, the damage analysis does not exist in isolation so consideration of the collision partners is essential for a CRASH type damage analysis (SMAC models the actual crushing of the vehicles every millisecond so the system is properly modeled)
We expect to prepare a publication on that in the near future.
