Field function definition
 
Hi,
in my project I need to define pressure as a function. The pressure should be 7000*(1+cos(2*pi*x/L)). L is the length of the pipe which is 100m. x is the position.
Here is my field function definition 7000*(1+cos(2*pi*$$PositionX/100)) .Can anybody tell me where is wrong? Thanks in advance

I think $$PositionX should be $$Position[0]

Also, youll have to manually type in the value for pi, STAR-CCM+ doesnt recognize it by default
