The msmac input file
When you opened My First Project, a grid display opened and the smac input file, My First Project.si5, automatically opened.
§ The medit editor remembers the last project you worked on and then also the last smac input file you used in the project
§ When you start medit it automatically opens the project and then the last project file used in the project.
§ When you switch to a different project, medit will open the last project file used in the project
If you are unfamiliar with the medit/msmac interface, please see our Introduction to the medit grid mode which explains the areas of the screen display. These demos assume you are familiar with medit and have gone through the Quick Start section.
Some items of interest:
§ Before proceeding with undertaking a msmac simulation reconstruction, please be sure to review the msmac Reconstruction checklist. You should assemble as much information on the accident as you can, then perform an traditional reconstruction by hand calculation techniques and then test and refine those reconstruction results with msmac.
§ In addition to the definition of the vehicles in the collision, there are now also ‘target’ inputs for the vehicle damage and the vehicle positions of impact and positions of rest.
o Note input cards 80 and 85, these define the measured damage of the two vehicles. The inputs for the Damage Measurements are explained in the appendix.
o Also note, from any card in medit, you can simply press the F1 key to bring up the msmac input file and the page related to the card that is current (the msmac input card which has current focus by mouse click or movement to the particular card). So for example, you could move to input card 80, field 1, and press F1 and the instruction for that card will automatically open in this help file window. Try it! After you have viewed the information be sure to select the Back button to return to this page.
o The damage measurements are displayed in the graphics and provide a direct comparison of the location of the damage to the simulated damage.
o The simulation also includes a 6 point damage ‘measurement’ of the smac simulation results for direct comparison with the 6 point damage measurements you can optionally provide.
o After you run throught the section HOW TO run the msmac graphics you will see the 6 point damage display of both measured and simulated/
§ Note also input card 87, this is the target positions at Rest. When you run msmac, a target position of rest will be displayed which can be used to compare the msmac simulated position of rest and the measured position of rest.
o Once you go through the procedure of running msmac below, try changing the impact speeds and you will see how the targets provide a good references for gauging the correlation of the simulation with the evidence.
o You can also include the target Positions of Impact, which are contained on input card 86. However in this example we did not use the position of impact option.
