008_topostruct3d - Material definition?

Hello,

I was wondering if there is any possibility to add a material definition to the 3D topology optimization. While other programs force me to pick a certain material, millipede doesn't.

Loads are applied in N/m^2, but shouldn't the load refer to a certain material?

Maybe someone can help me with that or clear this up for me.

Don't get me wrong, results are great. I'd just like to know if I missed something.

Thanks.
