CARD 90, mimic EDSMAC modifications The following options are provided to permit testing the effects of various changes made to the program by Engineering Dynamics Corporation (EDSMAC) and others.



90:1 
TrajVel 

If = 0, use SX,SY, default Calspan SMAC or msmac. If = 1, use U,V per some versions of EDSMAC. 


90:2 
TrajTabs 

The original SMAC program uses quadratic interpolation for input tables of braking and steering. EDSMAC uses linear interpolation. If = 0, use quadratic interpolation of input tables, per Calspan SMAC & msmac. If = 1, use linear interpolation per EDSMAC. Please note that for control input tables with less than 4 inputs, a linear interpolation will be used by default. 


90:3 
SetIND 

Calspan included modifications to the logic for the SETIND routine which determines whether front, side or corner logic should be used for the collision routine. msmac has further modified the logic to indicate left/right front/rear indicators to avoid possible crush logic errors for simulated severe impacts where the deflections approach or exceed the half width of the vehicle. If =0, Calspan SETIND routine. If =1, use original SETIND routine, per EDSMAC. If =2, msmac SETIND routine, with additional logic for simulations of very severe impacts.
