MIN

The MIN function returns the minimum of two expressions a1 and a2.

MIN(a1,a2) = a1 if a1 < a2
MIN(a1,a2) = a2 if a2 < a1

Format

MIN(a1,a2)

Arguments

 

a1	Any valid function expression.
a2	Any valid function expression.

 

Caution:

The MIN function is generally discontinuous. Use this function expression with care when you are specifying force or motion input.

Examples

SFORCE/1, ROTATIONAL, ACTIONONLY, I=21, J=11
, FUNCTION=MIN(0,-3*(AZ(21,11)-25D))

This SFORCE statement defines an action-only torque that acts at Marker 21 and acts along the z-axis of Marker 11. The torque is defined to always be negative through the use of the MIN function. Thus, the torque can only act to decrease the AZ rotation of Marker 21 with respect to Marker 11 (see AZ).
