WebFEniCS imposes these constraints this after assembling the stiffness matrix and load vector, by modifying entries associated to boundary DOFs. For this, we need to specify to FEniCS which DOFs are to be constrained (in this case all the DOFs on the boundary), and what they are to be constrained to (namely g). This is accomplished by invoking ... Webassign (receiving_func, assigning_func) Arguments. receiving_func ( Function) The receiving function assigning_func ( Function) The assigning function.
