Non uniform array spacing

Hello, I currently have a uniformly spaced array of 2d rectangles. I would like to instead create an array where the distances between rectangles varies according to some polynomial function based on the x coordinate corresponding to the rectangle's location.
I have been able to achieve this manually by creating many individual rectangles and creating a parameter for each rectangle's x location, but I am curious if there is an easier way to do this, particularly one that will allow me to more easily change the number of rectangles in the array.
Thanks!

To get a non-uniform spacing, you can use a Move feature instead of Array. In the x displacement text field, enter for example f({range(0,1,10)}), where f is a function, for example {range(0,1,10)}^2+{range(0,1,10)}. Then use a second Move feature to move the resulting moved objects in the y-direction.

Hi Ilan,
For completeness sake, and although it is probably overkill for your needs, I'll mention that you could also use a model method to create your geometry. See this blog post for an example.
A couple of other approaches would consist in using MATLAB and LiveLink for MATLAB (assuming your COMSOL license includes it), or the COMSOL Java API.
But Daniel's approach is by far the simplest one so there's no reason for you to look further if it works for you.
Best regards,
Jeff

Thank you both for your responses! I ended up needing MATLAB with LiveLink for a different purpose, so this was an easy problem to start learning it with.
