What is msmac? What is msmac2D?

msmac (also known as msmac2D) is the McHenry version of the SMAC 2D collision simulation program.
McHenry Software has marketed the program since 1994 and it is currently available. From our msmac page, some of the enhancements to msmac2D:
  • MSI has also extended and refined the original SMAC program to include (and all will be included in msmac3D, and more!):
    • Input and outputs in either Original, Metric or EDSMAC compatible. Capability to easily convert between the input/output units.
    • The capability to easily add detailed scene and vehicle graphical objects to the m-smac graphics display to permit an easy comparison of the physical evidence in individual accident reconstructions with the m-smac predicted responses. Please see our Demo page for sample of the graphics capabilities.
    • The ability to view and print the m-smac reconstruction in either an animated or static display including predicted damage. The predicted damage is displayed in animation while it occurs. Also, the m-smac animated view size, location and orientation may be changed interactively while the animation is being displayed and individual frames printed. Please see our Demo page for sample of the graphics capabilities.
    • Optional creation of CSV (comma delimited ASCII) datasets of the time-history of positions, velocities and accelerations from m-smac simulations for easy importation into spreadsheet programs and/or graphical programs to permit further analysis and/or the creation of graphical displays.
    • Increased collision modeling capabilities to permit 1 degree increments of radial vectors and an increase in the number of iterations permitted.
    • Optional specification of accelerometer location other than the center of gravity and the monitoring of the speed change (delta-V), acceleration and velocity at the optional location in addition to the center of gravity
    • Option to permit up to 2 Polygon Friction zones to permit the inclusion of irregularly shaped friction zones
    • Option to include the use of Impulsive Constraints to permit the modeling of vehicle interactions independent of crush forces (i.e., momentary interlock of vehicle structures)
    • Option to allow the specification of a Damage Interface origin independent of the vehicle center of gravity. This option avoids problems with other versions of SMAC (which have the damage interface only at the center of gravity), when the proximity of the damage is near the CG or very far from the CG.
    • Optional individual tire friction variation to permit simulation of the differences between peak friction coefficients between trucks and automobiles.
    • Steer degree-of-freedom option
    • Articulated vehicle(s) option
    • Option to simulate the interaction of the vehicle structure with barriers
    • Option to simulate the interaction of the vehicle structure with poles
    • Option to permit the simulation of rear wheel steer whether due to damage or 4-WD steering
and much much more...we will update this page/add new pages to include a updated features list soon!
