SetDefaultEffectiveCurvatureRadius()

void chrono::collision::ChCollisionInfo::SetDefaultEffectiveCurvatureRadius ( double  eff_radius )

static

Set the default effective radius of curvature (for SMC contact).

A collision system should evaluate this value for each collision using
    1/r_eff = 1/rA + 1/rB
where rA and rB are the radii of curvature of the two surfaces at the contact point.

If a collision system does not set this quantity, all collisions use this default value.
