Hi, I am trying to calculate the effective thermal expansion coefficient (CTE) of a composite. I am following a similar approach of homogenization example here . I need to apply a thermal strain similar to Eps in the example. Where it is different for different materials. So, how can i have a mat…

Create a tensor function space of cellwise constant variables (DG 0). [image] Different material properties in subdomains, tensor instead of scalar General How do you expect a tensor to be assigned to a scalar function space? The space ("CG", 1) contains one degree of fre…

Thanks for the response. One additional query can fenics do interpolation with cells argument. because i am using fenics.

No, that is not part of legacy fenics.

is there a way to do it in legacy fenics ?

Yes, in legacy fenics you can create a tensor for each Subdomain, for instance E_0 = Constant(0.5) E_1 = Constant(1.5) t = as_tensor(((E_0,0),(E_0, E_1))) and then use the integration measure to restrict integration, dx_c = Measure("dx", domain=mesh, subdomain_data=cell_marker) and use dx(j) to r…
