Dear Jimmy, Thank you for your reply. Yes, I can set up only one base function for each node. But the problem is that the example sets up two base functions for a two-component vector. FESystems fe_basis(FE_Q<dim> (2),dim,FE_Q<dim> (1),1), which the (2) means the vector has order-2 base functions. Best regards, Yuesu
