Hi:

I have constructed the metasurface geometry with matlab script. Now I'm trying to creat mesh, but as in the picture, there are way too many surface to select manually, and it seems that the number of every surface is not sequencial. So, How can I select all top surface of every pillar at once?

Thank you! Chang Chang

Hello Chang,

There are several tools in the GUI to create selections without picking entities one by one. They are accessed through the Model Builder under the Component > Definitions > Selections . One of them will select entities in a cylinder; that should work for your case. Note that you can also perform boolean operations on selections, etc, see Chapter 6 in the Reference Manual (Accessible through File > Help > Documentation, as always).

Best regards,

Jeff
