Hi,
Here are a couple of examples.
You will have to adapt them to your specific application, but that’s the general idea.
* colloidal_phC_hexa_pavement.fdt : a regular 3D hexagonal lattice or air holes in a dielectric material
* vbColloidal_phC.fdt : a randomly-distributed (in position and sizes) colloidal suspension of air bubbles in a dielectric material (like a sol-gel for example). This example uses visual basic scripting to position the bubbles.
I hope you will find them useful
