You can optionally specify different coefficients for vehicle 2

If this card not included, the default is to set the coefficients the same for vehicle 1 & 2

Coefficients of assumed parabolic variation of the program variable, C, as a function of maximum deflection.

where ∈=coefficient of restitution (see Reference 14)

The car body is to have some elasticity with the degree of restitution  varying non-linearly with the degree of deformation. Recommended values are .04606, 1.7547x10^-3,  and 1.6711x10^-5,  respectively. (To fit in the field of 8 columns the latter two should be entered as  1.7547-3 and 1.6711-5, which are interpreted as scientific notation).

Normal  C0=.04606, C1=1.7547x10^-3  , and C2=1.6711x10^-5

Plastic    C0=5.00x10^-5, C1=0.10  , and C2=50.0

Elastic    C0=1.000, C1=2.00x10^-5  , and C2=1.000x10^-10
