I am working on this project where I will be using Uranium Dioxide fuel rods for nuclear power plant fuel assembly. Fuel is in the form of rods and each rod is encapsulated by a cover called cladding, which is made of Zircloy, between them is a gap of helium gas.

I've made geometry, and now I want to perform the analysis but the things is I don't know how to add materials. I mean how can I specify which part of the geometry is made of what material?

I tried adding materials to Engineering Data, but no use. I will duplicate the previously present material and then will change the properties as per my need, but the things is, how can I tell workbench that this part of the geometry is made of that certain material.

A little help will be appreciated,
