Adds the additional matrix mat_name to this system.
Only allowed prior to assemble(). All additional matrices have the same sparsity pattern as the matrix used during solution. When not System but the user wants to initialize the mayor matrix, then all the additional matrices, if existent, have to be initialized by the user, too.
This non-template method will add a derived matrix type corresponding to the solver package. If the user wishes to specify the matrix type to add, use the templated add_matrix method instead

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. If non-default Parameters are to be used, they can be provided in the parameters argument.

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.

This function computes one basis function for each rhs term.
This is useful in some cases since we can avoid doing a full greedy if we know that we do not have any "left-hand side" parameters, for example.

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.

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

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.

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.
This is the crucial function in the Offline stage: it generates 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.

Writes additional data, namely vectors, for this System.
This method may safely be called on a distributed-memory mesh. This method will create an individual file for each processor in the simulation where the local solution components for that processor will be stored.
This method implements the output of the vectors contained in this System object, embedded in the output of an EquationSystems<T_sys>.

for each additional vector in the object
10.) The global additional vector, re-ordered to be node-major (More on this later.)
Note that the actual IO is handled through the Xdr class (to be renamed later?) which provides a uniform interface to both the XDR (eXternal Data Representation) interface and standard ASCII output. Thus this one section of code will read XDR or ASCII files with no changes.

This vector is used only when reading in a system from file.
Based on the system header, it keeps track of any index remapping between variable names in the data file and variable names in the already-constructed system. I.e. if we have a system with variables "A1", "A2", "B1", and "B2", but we read in a data file with only "A1" and "B1" defined, then we don't want to try and read in A2 or B2, and we don't want to assign A1 and B1 values to different dof indices.

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.

We may optionally want to use the "energy inner-product" rather than the inner-product assembly specified in inner_product_assembly.
In this case the inner-product will be defined by sum_q^Q k_q * A_q. Here we provide the k_q values that will be used. (Note that a true "energy-inner product" would obtain the k_q from the theta_q's, but this is different for each parameter choice so we just provide a fixed set of k_q's here to ensure that the inner-product is parameter independent)
