I have the most simplest composite domain with two 1x1 subdomains connected by an interface at y=1.
Now, this interface satifies continuity condition for the displacement and flux as they do. And also,. I have two different wave velocity (i.e., young's modulus and density) for the two subdomains. I can't seem to find how to create this interface and define the wave velocities correctly.
Can anyone help me to find appropriate options?
