Component Wise Dirichlet BC

Thanks for the share Dokken. I fixed the issue with:

Setting vector component-wise Dirichlet BCs

Hi I have been successfully running a nonlinear mixed vector field problem (simple uni-axial tension of a rod) using a non-homogeneous Dirichlet boundary condition incrementally applied as a vector, i.e [ u_x, u_y, u_z] = [ t*1.0, 0.0, 0.0 ] at the right end of the rod (the left end is clamped): msh = mesh.create_box(MPI.COMM_WORLD, [np.array([0.0, 0.0, 0.0]), np.array([L, H, H])], [20, 1, 1], mesh.CellType.hexahedron) P1 = ufl.VectorElement("CG", msh.ufl_cell(), 2, dim=3…
