Hi all, I am trying to compute the sensitivity with DOLFINx based on the adjoint method ( lecture_12_sensitivities.pdf (fenicsproject.org) ). Given: (1) PDE: \mathbf{R}(\mathbf{u})=\mathbf{0} (2) Variable m (3) Objective functional g(m,\mathbf{u}(m)) Compute the sensitivity: \dfrac{\text{d}g(m,\…

The problem with your code is that you start using scipy matrices to do the operations. If you continue using ‘pure’ dolfinx/ufl/petsc operations, everything works as expected. Consider the minimal code below: import dolfinx import ufl from dolfinx.generation import RectangleMesh from dolfinx.mesh…
