Adds the additional vector vec_name to this system.
All the additional vectors are similarly distributed, like the solution, and initialized to zero.
By default vectors added by add_vector are projected to changed grids by reinit(). To zero them instead (more efficient), pass "false" as the second argument
If the vector already exists, the existing vector is returned. after any upgrade to the projections or type has been made. We only handle upgrades (projections false->true, or type PARALLEL->GHOSTED) in this fashion, not downgrades, on the theory that if two codes have differing needs we want to support the union of those needs, not the intersection. Downgrades can only be accomplished manually, via set_vector_preservation() or by setting a vector type() and re-initializing.

This function enables the user to provide a shell matrix, i.e.
a matrix that is not stored element-wise, but as a function. When you register your shell matrix using this function, calling solve() will no longer use the matrix member but the registered shell matrix instead. You can reset this behaviour to its original state by supplying a nullptr to this function.

Projects arbitrary boundary functions onto a vector of degree of freedom values for the current system.
This method projects an arbitrary boundary function onto the solution via L2 projections and nodal interpolations on each element.
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.

Compute the terms that are combined ‘online’ to determine the dual norm of the residual.
Here we compute the terms associated with the right-hand side. These terms are basis independent, hence we separate them from the rest of the calculations that are done in update_residual_terms. By default, inner product terms are also computed, but you can turn this feature off e.g. if you are already reading in that data from files.

var at the physical point p in the mesh, without knowing a priori which element contains p, using the degree of freedom coefficients in sol (or in current_local_solution if sol is left null).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.

This function is called from add_scaled_matrix_and_vector() before each element matrix and vector are assembled into their global counterparts.
By default it is a no-op, but it could be used to apply any user-defined transformations immediately prior to assembly. We use DGFEMContext since it allows for both DG and continuous Galerkin formulations.

Similarly, provide an opportunity to post-process the truth solution after the solve is complete.
By default this is a no-op, but it could be used to apply any required user-defined post processing to the solution vector. Note: the truth solution is stored in the "solution" member of this class, which is inherited from the parent System class several levels up.

Constrain the new vector using the requested adjoint rather than primal constraints if is_adjoint is non-negative.
This method projects a solution from an old mesh to a current, refined mesh. The input vector old_v gives the solution on the old mesh, while the new_v gives the solution (to be computed) on the new mesh.

This method creates a projection matrix which corresponds to the operation of project_vector between old and new solution spaces.
Heterogeneous Dirichlet boundary conditions are not taken into account here; if this matrix is used for prolongation (mesh refinement) on a side with a heterogeneous BC, the newly created degrees of freedom on that side will still match the coarse grid approximation of the BC, not the fine grid approximation.

For each of the system's quantities of interest q in qoi[qoi_indices], and for a vector of parameters p, the parameter sensitivity Hessian H_ij is defined as H_ij = (d^2 q)/(d p_i d p_j) This Hessian is the output of this method, where for each q_i, H_jk is stored in hessian.second_derivative(i,j,k).
Note that in some cases only current_local_solution is used during assembly, and, therefore, if solution has been altered without update() being called, then the user must call update() before calling this function.

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].
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.

Allows one to set the QoI index controlling whether the vector identified by vec_name represents a solution from the adjoint (qoi_num >= 0) or primal (qoi_num == -1) space.
This becomes significant if those spaces have differing heterogeneous Dirichlet constraints.
qoi_num == -2 can be used to indicate a vector which should not be affected by constraints during projection operations.

Train the reduced basis using the "Greedy algorithm.".
Each stage of the Greedy algorithm involves solving the reduced basis over a large training set and selecting the parameter at which the reduced basis error bound is largest, then performing a truth_solve at that parameter and enriching the reduced basis with the corresponding snapshot.
resize_rb_eval_data is a boolean flag to indicate whether or not we call rb_eval->resize_data_structures(Nmax). True by default, but we may set it to false if, for example, we are continuing from a previous training run and don't want to clobber the existing rb_eval data.

Train the reduced basis using Proper Orthogonal Decomposition (POD).
This is an alternative to train_reduced_basis(), which uses the RB greedy algorithm. In contrast to the RB greedy algorithm, POD requires us to perform truth solves at all training samples, which can be computationally intensive.
The main advantage of using POD is that it does not rely on the RB error indicator. The RB error indicator typically stagnates due to rounding error at approximately square-root of machine precision, since it involves taking the square-root of a sum of terms that cancel. This error indicator stagnation puts a limit on the accuracy level that can be achieved with the RB greedy algorithm, so for cases where we need higher accuracy, the POD approach is a good alternative.

Flag which tells the system to whether or not to call the user assembly function during each call to solve().
By default, every call to solve() begins with a call to the user assemble, so this flag is true. (For explicit systems, "solving" the system occurs during the assembly step, so this flag is always true for explicit systems.)
You will only want to set this to false if you need direct control over when the system is assembled, and are willing to track the state of its assembly yourself. An example of such a case is an implicit system with multiple right hand sides. In this instance, a single assembly would likely be followed with multiple calls to solve.
The frequency system and Newmark system have their own versions of this flag, called _finished_assemble, which might be able to be replaced with this more general concept.

Boolean flag to indicate whether we store a second copy of the basis without constraints or dof transformations applied to it.
This is necessary when we have dof transformations and need to calculate the residual R(U) = C^T F - C^T A C U, since we need to evaluate R(U) using the untransformed basis U rather than C U to avoid "double applying" dof transformations in C.
