FrequencySystem
provides a specific system class for frequency-dependent (linear) systems.
Generally two solution flavors are possible:
ini()
. Also provide functions _assemble_fptr
and _solve_fptr
that should compute the element contributions, and simply add these contributions to give the frequency-dependent overall matrix, respectively. For details see the examples section._solve_fptr
which assembles the overall, frequency-dependent matrix for the current frequency given in the parameter section of EquationSystems<FrequencySystem>
named "current frequency". For this to work, only provide one frequency.Definition at line 63 of file frequency_system.h.

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.

a matrix that is not stored element-wise, but as a function. When you register your shell matrix using this function, calling solve()

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].
Uses the forward sensitivity method.
Currently uses finite differenced derivatives (partial q / partial p) and (partial R / partial p).

at the physical point 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 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.

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.

Sets the system to be "basic only": i.e.
advanced system components such as ImplicitSystem matrices may not be initialized. This is useful for efficiency in certain utility programs that never use System::solve(). This method must be called after the System or derived class is created but before it is initialized; e.g. from within EquationSystems::read()

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.

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>.
9.) The global solution vector, re-ordered to be node-major (More on this later.)
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.

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.

This class handles all the details of interfacing with various linear algebra packages like PETSc or LASPACK.
This is a public member for backwards compatibility reasons, but in general it's better to use get_linear_solver() to access this member, since that function will also handle initialization if it hasn't already been taken care of.
