Adds the additional matrix mat_name to this system.

This function loops over the mesh and applies the specified interior and/or boundary assembly routines, then adds the scaled result to input_matrix and/or input_vector.

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.

var at the physical point p in the mesh, without knowing a priori which element contains p.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 method creates a projection matrix which corresponds to the operation of project_vector between old and new solution spaces.

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.

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.

Vector storing the residual representors associated with the right-hand side.
These are basis independent and hence stored here, whereas the Aq_representors are stored in RBEvaluation

Vectors storing the residual representor inner products to be used in computing the residuals online.
We store the Fq representor norms here because they are independent of a reduced basis space. The basis dependent representors are stored in RBEvaluation.

A boolean flag to indicate whether or not the Fq representor norms have already been computed — used to make sure that we don't recompute them unnecessarily.

Boolean flag to indicate whether we impose "fluxes" (i.e.
element boundary contributions to the weak form) on internal element boundaries in the assembly routines.

We store an extra linear solver object which we can optionally use for solving all systems in which the system matrix is set to inner_product_matrix.

We keep an extra temporary vector that is useful for performing inner products (avoids unnecessary memory allocation/deallocation).

The LinearSolver defines the interface used to solve the linear_implicit system.
This class handles all the details of interfacing with various linear algebra packages like PETSc or LASPACK.

The system matrix.
Implicit systems are characterized by the need to solve the linear system Ax=b. This is the system matrix A.

Values of the quantities of interest.
This vector needs to be both resized and filled by the user before any quantity of interest assembly is done and before any sensitivities are calculated.

This boolean flag indicates whether or not the training set should be the same on all processors.
By default it is false, but in the case of the Empirical Interpolation Method (RBEIMConstruction), for example, we need the training set to be identical on all processors.

In some cases meshes are intentionally created with degenerate sides as a way to represent, say, triangles using a hex-only mesh.
In this situation we should detect and skip any degenerate sides in order to prevent zero or negative element Jacobian errors.

Boolean flag to indicate if we skip residual calculations in train_reduced_basis.
This should only be used in special cases, e.g. when we know a priori that we want exactly one basis function and hence we do not need the residual based error indicator.

By default, the system will zero out the matrix and the right hand side.
If this flag is false, it is the responsibility of the client code to take care of setting these to zero before assembly begins
