Split plane gap Query

I have a Query regarding Split plane

In a split power plane, i want to check how the split gap is related to induced voltage(noise) in the other plane.

for example:there are 2 shapes in a perticular power layer - say 3v3 and 5v0, if the split gap between the two shapes is varied how the induced voltage will vary in the other(lower voltage) shape.

We generally use 20-40 mil gap as a rule of thumb. but i need to verify this, Can we make this scenario in hyperlynx? please suggest me how to verify the split gap?
