Drawing a repeated diamond pattern?

Hi all,
I am trying to make a model in which a repeated diamond pattern is cut out of an object. Basically a 3D rectangle with diamond shaped pores, the long axis of the diamonds being parallel to the length of the rectangle. I think this is done with an array? Does anyone know how to make this model?
Thank you for any help

Hi
in the COMSOL geometry mode you have the "copy" command, instead of just typing in 1,1,1 for x,y,z, type in:
range(0,1,3) range(0,1,3) range(0,1,3) for x,y,z or
0 1 2 3 for each x,y,z
then you will get the original one at 0,0,0 and 3 copies at 1,1,1. 2,2,2 3,3,3
I hope I'm clear ;)

Good luck

That makes sense. I have a similar question, but it brings up different challenges. How would you make "infinitely long" patterns? For example consider the following scenario. If I had two cylinders of different diameters (S-small and L-large) that are stacked end-to-end, how would I repeat the pattern in the z-direction? The scheme would look something like:
r-dir
^
| ... S-L-S-L-S-L-S-L-S-L-S-L ...
- - - - - - ->
z-dir
Obviously, I could create many many duplicated features to achieve a similar result, but this is very inefficient. The goal is to avoid edge effects.
Thanks!
