Matlab assign geometry to materials

I desperatly try to run matlab script to simulate a 2d axissymmetric simulation.
The geometry objects and the materials were easily created. The problem is, that I struggle to assign the geometry to the materials.
Using the model.material('mat1').selection.set() seems intuitive, however I have no idea how I get the domain
information from the geometry objects.
Is there a simple way to assign the geometry to the materials?

Hi,
to learn these things, link the syntax, you better open Comsol GUI, define few simple features in a new model and export a .m file. There you'll read the correct syntax to apply your material!
hope it helps,

Hi!
Thanks for the post.
I already did it that way. The problem is, that the code shows absolut domain ids, f.e. something like model.material('mat1').selection.set([1 5 81 88]);
The problem is, that i don't know which object is 1 or 5 or so on. So I have to extract this information out of the geometry objects and that is exactly the problem I can't achive.

I understand and I agree with you.. as far as I know there is no way to know the geometries ids before/while Comsol builds the geometry. I'd also say this makes perfectly sense..
What I do circumvent this problem is to create groups of objects.; for my applications this suffices.
Sorry, I can't help much..
