Projects arbitrary boundary functions onto a vector of degree of freedom values for the current system. Only degrees of freedom which affect the function's trace on a boundary in the set b are affected. Only degrees of freedom associated with the variables listed in the vector variables are projected. The function value f and its gradient g are user-provided cloneable functors. A gradient g is only required/used for projecting onto finite element spaces with continuous derivatives.

Loop over the dofs on each processor to initialize the list of non-condensed dofs. These are the dofs in the system that are not contained in global_dirichlet_dofs_set and are not subject to constraints due to adaptive mesh hanging nodes, periodic boundary conditions, or Dirichlet boundary conditions.

Most users will not need to use the global_condensed_dofs_set argument; simply call initialize_condensed_dofs() after any time the EquationSystems (and therefore its constraint equations) gets initialized or reinitialized.

Returns
The value of the solution variable var at the physical point p in the mesh, without knowing a priori which element contains p.
Note
This function uses MeshBase::sub_point_locator(); users may or may not want to call MeshBase::clear_point_locator() afterward. Also, point_locator() is expensive (N log N for initial construction, log N for evaluations). Avoid using this function in any context where you are already looping over elements.

Because the element containing p may lie on any processor, this function is parallel-only.

By default this method expects the point to reside inside the domain and will abort if no element can be found which contains p. The optional parameter insist_on_success can be set to false to allow the method to return 0 when the point is not located.

Projects arbitrary functions onto the current solution. The function value f and its gradient g are user-provided cloneable functors. A gradient g is only required/used for projecting onto finite element spaces with continuous derivatives. If non-default Parameters are to be used, they can be provided in the parameters argument.

This method projects an arbitrary function onto the solution via L2 projections and nodal interpolations on each element.

Solves for the derivative of each of the system's quantities of interest q in qoi[qoi_indices] with respect to each parameter in parameters, placing the result for qoi i and parameter j into sensitivities[i][j].

Note
parameters is a const vector, not a vector-of-const; parameter values in this vector need to be mutable for finite differencing to work.

Automatically chooses the forward method for problems with more quantities of interest than parameters, or the adjoint method otherwise.

This method is only usable in derived classes which override an implementation.
