Kinematics issue

Hi,

I have an urgent issue in Kinematics in an four bar mechanism Please help me out. I want to define a law with the below formula :

theta = theta1 + omega * t + 1/2 ( alpha * t^2 )

where theta is the fundtion to be measured

theta1 = angle at the starting point.

omega = ang.velocity of the bar ( 4 deg/s )

alpha = angular accelaration ( 1 deg/sec^2 )

t = time

this is a four bar mechanism and we are trying to measure the speed and accelaration of the slider in this mechanism.

The issue is CATIA is not recognising the formula when we try to simulate using laws.


Awaiting your reply at the earliest.
