Hi Wonseok,
I think you can make any physical property to be dependent on the space coordinates (x,y,z, for instance).
For instance, if you want to assign a space dependent Young modulus, you just have to specify it in your subdomain settings. Call it "E" and specify its space dependence as a function written in "Options/Expressions/Sudomain expressions.
Clearly the same holds for BCs, load, initial conditions and so on.
I hope this help.
