The following example demonstrates the input format for the m-smac barrier option. (The input cards are taken from the m-smac input file ADVSAMP2.Si5 which is contained in the project file ADVSAMP2.prj). In this example, the barrier location is specified on card 27 and is located in quadrant 1 represented by a line which passes through points (X,Y) (96",480") to (156",240"). Twelve hardpoints are specified on card 27 and their locations on the vehicle which interact with the barrier are specified on card(s) 29.
The following are the card inputs for the barrier option:
96. 480. 156. 240. 1200. 10. 0.4 17.6 12. 27
0.10 0.0 0.0 0. 28
74.5 34.2 74.5 14.2 74.5 -14.2 74.5 -34.2 0 29
-110.4 34.2 -110.4 14.2 -110.4 -14.2 -110.4 -34.2 1 29
34.5 34.2 -34.5 34.2 34.5 -34.2 -34.5 -34.2 2 29
