I am looking for the Dolfinx equivalent of the .apply method() for Dolfin’s DirichletBC class, Dolfin Docs , as used for example in bc1 = DirichletBC(V.sub(0), Constant(0.0), point1, method="pointwise") bc2= DirichletBC(V, r, right) u_ = Function(V) u_.vector()[:] = 1 bcs = [bc1,bc2´] [bc.apply(u_.…

[image] Mark: I am using Dolfinx 0.0.6, and it seems to me that a class dolfinx.fem.bcs.DirichletBC still existed, as it is the output of type called on a dirichlet boundary condition. Where do you see that? Here is the source code: https://github.com/FEniCS/dolfinx/blob/v0.6.0/python/dol…

See: Boundary conditions about Mixed space - #2 by dokken
i.e. you can use dolfinx.fem.petsc.set_bc
