### msmac3D Ver 4.5.5 FEATURE HIGHLIGHTS, AVAILABLE NOW!

Mar 13, 2024: Update 4.5.5 is uploaded! This lists some of the many enhancements
• Refinement of NEW Sequential Inputs
• Inputs for Acceleration/Deceleration 2D v 3D
• When comparing 2D v 3D simulation an issue with acceleration was enhanced to make the inputs correlate between 2D v 3D simulations.
• FIRST: In 3D simulation there is an option to set the decel/accel based on static weight or dynamic weight
• for Sequential inputs (below) for Tables 8 & 9 set field 9, set to 1)

• For 3D dynamically applying the decel or accel makes sure dynamic changes in the weight distribution arre accounted for as the vehicle moves on 3D terrain particularly if it pitches and/or rolls. (in 2D there is no pitch or roll)
• SECOND: In 3D the actual input for fractional percentage decel or accel applied is an applied as a torque.
• So the dynamic rolling radius needs to be considered and for acceleration the effective coefficient of friction needs to be considered.

These differences could make 2D v 3D simulation comparisons slightly different since, for example, if the nominal coefficient of friction was 0.75, a 0.2 G acceleration in 3D would be applied as 0.2 G * 0.75 G friction or 015 Gs
The application of acceleration has been modified to apply the acceleration factors with the consideration of the nominal friction coefficient.
It is recommended (and the defaults are changed) that the braking/acceleration tables (8 & 9) and/or the Suequential input tables ALWAYS use the Dynamic Braking option in 3D by setting it to 1. (for 2D it will make no difference)
• Time Shift of Display
• For Point List inputs/animation
when used while comparing simulation (like direct input of pc-crash and virtual crash) we have added a 'time shift to the inputs
so
you can directly input the time per the output of the other simulation programs and then simply enter a 'time shift' so it can be synched with a msmac3D simulation.
For example, for instantaneous momentum exchange simulation programs the time 0.0 is generally the 'time of maxomum engagement' whereas in msmac3D since we simulate the forces and moments of the entire crash, the actual time of 'maximum engagement' can be at 0.1 to .5 seconds (since we reconmened startign the crash simulation with the vehicles NOT in contact)

• For Point List Inputs/Animation Model Resize Options
• For Point List inputs/animation
Added the option to get dimensions for a model used in point list animation by
• manually setting the dimensions
• setting per the specifications database
• setting to a vehicle specifications for a vehicle in an si5 file

• Zoom ALL button
• Simple button to allow you to ZOOM ALL in the graphics overhead view.
You can also, of course, set up to 8 user set views, this is simply to allow quick zoom out to extents.

Feb 13. 2024 Update 4.5.4 uploaded! This lists some of the many enhancements
An email has been sent out to ALL McHenry Software Licensees with link to update files so please check your inbox This link will be updated with links to videos in the near future.
Stay Tuned!
Here's a quick video of some new features
Here's a recent msmac3D crash reconstruction demonstrating some of the many simulation and graphics capabilities.
Here is a HOWTO easily display pc-crash/virtual crash results directly in msmac3D 3D graphics using the new Point List animation for direct comparisons or results. Point List Animation can also be used to add more vehicles to the graphical environment.
HOWTO Video to take EDR data and use direct in msmac3D Simulation and create comparison charts and graphics
more to come soon! Stay Tuned!

4.5.4 update Feb 13, 2024
We added ability to change/check Lence angle (for wide or telephoto lens)
graphics variables.png (42.38 KiB) Viewed 9195 times
The Lence angle when all the way to the left is infinite (so orthogonal)
all the way to right is wide angle.
move the slide bar to change the lens.
Clicking on the line adjacent to the slider changes the amount by 1 degree at a time.
4.5.4 change is to retain the 'last view' lence angle (all Set Views retain lence angle but the last view, if not a set view, did not)
