I tried to create define Dirichlet BC as a spatially varying vector. To do so, I defined a SpatialCoordinate and wrapped the function is ufl.as_vector. The MWE from dolfinx import mesh domain = mesh.create_unit_square(MPI.COMM_WORLD, 8, 8, mesh.CellType.quadrilateral) V = functionspace(domain, ("L…

Interpolate the u_D into the function space of the bc. This is for instance covered in: Diffusion of a Gaussian function — FEniCSx tutorial
