Global eqn. Help

I'm having some issues with a global equation, specifically with the initial value assignment.
I have a global equation governing a prescribed mesh displacement (rotation). The equation contains a cos(u) term and a sin(u) term so it is 0 at integer multiples of pi/2. The initial value for u, u_0, is set at 30deg (0.8ish rad).
When I ran the simulation, no rotation occurred, so I added a global variable probe on u. At t=0 the table shows u = 1.0916E-4 rad, which is very much not the value I've entered as the initial value for u. The rest of the table is made up of values tending even closer to 0; as far as I can tell, no rotation is observed because the equation is basically 0 for the duration. What I don't understand is why the value for u_0 is not the value I've entered...
