Dear Daniel, You can obtain local DoF values from a global FE vector using > FEValuesBase::get_function_values [1], create the right-hand side locally > as you wish and use ConstraintMatrix::distribute_local_to_global to create > the global right-hand side. This is outlined in step-21 for example. >
Considering for example the term [*M*+k*theta**A*]**U* in my right-hand side, since the mass matrix(M) and laplace matrix(A) in the local level have the size of *dofs_per_cell * dofs_per_cell* I need to have a local solution vector to multiply with them. However, FEValuesBase::get_function_values returns solution values at quadrature points in a vector with the size of *n_q_points*. I was wondering if there is a function that returns nodal solution values for every cell. Thank you very much for your time.
