array of objects with variable spacing

Hi to all,
I'm working on a 2D geometry and I would like to generate an array of objects whose distance varies according to the following linear law: d =d0+m*X where d0 and m are constants and X is the X coordinate.
I've tried to insert such a law in the "Displacement Field" of the Array function, but an error message appears, because of the presence of the X.
Thus, I've tried to create multiple copies of the same object, exploiting the fact that, according to Comsol manuals, it is possible to create several copies by entering a comma-separated list of displacements in the "Displacements" field.
But also in this way, the copy failed and the error was "Illegal input displacement matrix".
Does anyone know how to fix this problem, and above all, how to create such an array?
Thanks in advance for the answers.
Alessandro

Hi
I agree that it would be interesting to distribute an array with equation based separations (in particular for diffractive optics geometry generation).
Unfortunately I do not know (now) how to do it int he GUI, with matlab it should be rather easy (it's worth a mail to "suggest" )

Good luck
