The geometry size affect the implementation of initial values(Initial Conditions)?

the Random Function is: Function name: init, Number of arguments: 2, Distribution: Uniform, Mean: 0.5, Range: 0.02,
The Geometry is a square,
When I click the compute button, strange thing happened to the Results, that is
When the side length of the square is 1[cm], the compute result at time 0 is the same as the initial values (the Random function),
but when I reduced the side length, for example, set the side length of the square as 100[um], the result at time 0 is different from the initial values.
It was so strange! Why the geometry size affect the result at time 0 (or the initial values)?
I use the PDE general form, comsol 4.0
Thank you!
