This is a duplicate copied from Q&A on msmac3D for convenience:
July 1, 2014: To supplement the information on msmac3D as questions come in from our current licensees considering msmac3D this post will contain Q& A's to help clarify the information on msmac3D.

- If you have any questions on msmac3D please send to us at msmac3D@mchenrysoftware.com
Also be sure to see: Q: When will there be training on msmac3d? I always feel more comfortable testifying when I can say I was "trained" in the use of the software. When can I take a course ?- A: We plan to add a training schedule for the late fall/early winter. We will post up some tentative dates in the next couple of months. We are designing msmac3D to be an easy and a seamless transition from msmac2D (or any smac2D program):
- the input requirements for 3D are simple you can also customize ALL the 3D inputs (this allow folks to rerun inputs from other 3D programs for comparisons).
- 1) Program inputs
- 2) Program outputs
- 3) Animation / visualization fidelity. StudioMax /3ds models ?
- A: Msmac3D currently works exactly like msmac2D. All you do is insert information on the Center of Gravity (CG) height, Overall Height (OH), and Bumper Height and then simply click run the same way you run msmac2D. Then you look at the results in 3D OR 2D. All our existing 2D graphics and animation program will work with the 3D program.
If you have specifications for 3D, like the MVMA specifications for a particular vehicle or similar, which may contain suspension properties and stop/extension distances, etc., you can simply input the known values to override the defaults. You can change some, none or all of the HVOSM type inputs.
No cumbersome need to insert All the inputs, they are automatically calculated for you and using our approximation techniques we are doing very well on validation. (We expect to complete publication of the approximation techniques and validations in upcoming scientific publications to be available shortly after release of the program)
In summary:- Inputs:
- The same as msmac2D except for 3D you will also have to provide the Center of Gravity (CG) height, Bumper height and overall vehicle height (OH). You can also change anything else.
- Outputs:
- The same as msmac2D outputs and same as 2 HVOSM simulations outputs. All in report form and comma delimited (CSV) output form. So you can chart variables v time, with our charting function or any spreadsheet program
- Animation:
- 3D graphics. Similar to the Princess Di and/or the Jeep rollovers posted up. Note we won’t have all the super duper special effects, just simple good quality 3D graphics.
- Inputs:
- A: Yes. all software will be transmitted electronically and DVD backups on request. We also plan on changing the licensing scheme for ALL our software to be web-based so you will no longer have to use a dongles. More on that in the next month or so.
Q: I found copies of the four HVOSM manuals from February of 1976. PB 267 401, PB 267 402, PB 267 403,PB 267 404. I will be looking through these to develop an understanding of the program.- A: An important point: there is no complicated setup for 3D!
The minimum you need is only bumper height, CG height and overall height.
We do the rest.
The manuals and inputs are only if you have specific values you want/need to change (like moments of inertia? Suspension properties? Etc)
We automatically calculate the 3D inputs for you.
Part of our validation process will be a demonstration of how the vehicle responses match full scale tests results with the automatic approximations. Also for a summary of research we have done an background on the HVOSM and msmac3D programs, see our publications:
