WebWith u = Function(V) we get u as a vector-valued finite element function with three components for this 3D problem.. Constant vectors . For the boundary condition u = (0, 0, 0) u = (0, 0, 0), we must set a vector value to zero, not just a scalar.Such a vector constant is specified as Constant((0, 0, 0)) in FEniCS. The corresponding 2D code would use … WebMar 11, 2024 · 1 In the Fenics documentation, it is mentionned that DirichletBC takes three arguments, the first one is our function space V, the next is the boundary condition value and the third is the subdomain indicator which is information stored in the mesh. Where is the subdomain indicator in the mesh file? How do I change it's value?
