I think this is such a function:

$ ReplicateFunction =
function {
  OtherFunction(
    x % Xspacing - if(x, 1, -1)*Xspacing/2,
    y,
    z % Zspacing - if(z, 1, -1)*Zspacing/2
  )
}


And I think this cointaned_by statement can be 
used with your iso-surface when the above 
function is used:

  contained_by {
    box {
      -<Xnr, 3.5, Znr>*<Xspacing, 1, Zspacing>,
       <Xnr, 1.0, Znr>*<Xspacing, 1, Zspacing>
    }
  }


Best regards,

Tor Olav
