How to use various material properties in a PDE model

What I have is a model with a number of domains, say like a piece of metal in air. I want to use the same equation in both domains, but they obviously have different properties. how can I do that in functional form.

Thank you

Cited from the documentation:

You can specify the coefficients for each subdomain independently. This makes it easy to specify, e.g., various material properties in one PDE model. The PDE to be solved can be specified by clicking the PDE button or by selecting PDE Specification from the PDE menu. This brings up a dialog box.

Best wishes

Hello Torsten,

I want to do it in functional form, i.e. without opening the PDE toolbox. Do I have to insert let's say createpde(3) and then insert coefficients as 3X3 matrices ?

Were you able to it?
