Assigning Different Material without Changing Mesh

Hello everyone;
I want to assign a material for a very small domain within a large domain without changing the meshing. For instance let's say you have a very big solid cube of aluminum and you want a smaller golden cube within the bigger cube. To do that, I draw the cubes within each other, but meshing gets very intense on the regions where these two cubes intersect. I don't want that. I want a homogenous meshing across all domains. How can I do that? Any help is appreciated.

You can do it by giving the material properties as function of spatial dimensions. You can use logical operators to specify material properties such if(sqrt((x-xo)^2+(y-yo)^2)< r_particle, Mat_p, Mat_d) where, the xo, yo are the origin of particle of radius 'particle.
However, a sharp change in material properties can make solver convergence difficult.
