Creo Simulate

Good Afternoon,

I am trying to idealize loads on a simply supported beam as per the screenshot. The beam is sketched using two lines to idealize the loads.

I am having trouble with the load on the second section of the beam.

I am using the function of Coordinates to define the load which reduces from 6N/mm to zero, this function is described as 6-(6/3000)*X

Creo seems to ignore the function and the load is opposite to the defined function, as per the screen shot.

Can someone please explain why this occurs and how to avoid or resolve this issue?

Thanks in advance.

Rob
