Hi, I want to calculate the fowllowing integral, [Screenshot from 2024-01-15 15-37-49] by assembleing the form element = create_element("Lagrange", "interval", 1) E = Coefficient(element) energy = E * E * dx and I creat the form as fowllows: auto el = std::make_shared<Form<T>>(fem::create_form<…

[image] WjjSteve: auto el = std::make_shared<Form<T>>(fem::create_form<T>(*form_Poisson_1D_Q1_el, {V}, {{"E", E_}}, {}, {})); Have a look at: FEniCS/dolfinx/blob/0a3582b6d485f1e6bff6e54c9b44e94adeff0450/cpp/demo/poisson_matrix_free/main.cpp#L218-L220 auto E = …
