While I am not an expert in GATE, it seems that the "generic repeater" would be adequate for your situation. Did you try it and if yes, was there a problem with that approach? </div>

<div dir="ltr">Dear GATE Experts,
<div><br>
</div>
<div>In GATE, we have repeated structures, like a cubic array, linear repeaters, etc which repeat the same geometry with a given number of repetitions along the x and y-axis but for all repeating structures the material is same, i.e<font color="#000000"> lead
material for hexagonal holes to develop a collimator in below picture</font>.</div>
<div><img alt="image.png" width="498" height="393" src="cid:17983197210cb971f161"><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>If we want to repeat the geometrical structure same as the above cubic array, but with two materials rather than one. For example, in the below image, the magenta color squares have material lead while black squares have material Air. All squares have
identical geometry but some have lead material and some have Air material according to user-defined pattern.</div>
<div><img alt="image.png" width="498" height="409" src="cid:17983197210cb971f162"></div>
<div><br>
</div>
<div><b>Can somebody let me know that how can we repeat the same geometrical structure with material one at some places and other material at other places as I showed you in the above image?</b></div>
<div><br>
</div>
<div>I build this geometry in above figure manually like</div>
