I am trying to create a rectangular box that contains another rectangular box inside.

Both boxes have different material properties (different concrete strengths), can anyone advise me on the best way to construct a model for this?

I have been using the Box tool in Primitives and using the Add Frozen. Is this the best way to go about this and how do you suggest I connect these Boxes?

I will be creating and testing a physical model (first casting the inner box, and then casting another box around the inner one). My task in to model this in Ansys and try and return similar results.

Aplogies if this is a bit wordy, I am new to Ansys/forums.

Any Help would be hugely appreciated,Thanks!!
