Multi-material problem/Subdomains

[david-boehm]

Is there a easy possibility to define multiple materials/subdomains on a body. From looking at the crystal_plasticity application example it seams it should be somehow possible, yet I am having troubles modifying the linear_elasticity demo a multi-material/subdomain problem. Reading chapter 4 of your paper Fig. 16 suggest that the definition of a soft/hard material combination is possible? Can this example be found somewhere?

You may refer to the topology optimization example and use a variable like theta to control the moduli for different parts of your domain.
