Implements the Newmark time integration scheme.
This class contains a specific system class. It provides an implicit time integration scheme known as the Newmark method.
In the algorithm implemented here the system is solved for displacements. Currently the Newmark scheme is implemented for constant time step sizes only. This time step is stored in the EquationSystems
parameter named "Newmark \p time \p step"
. For the case of constant time steps the matrix only has to be assembled once, whereas the rhs has to be updated in each timestep. Default values of the Newmark parameters alpha
and delta
used for time integration are provided. For details refer to the examples section.

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.

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

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 adjoint_solve() and the adjoint sensitivity method.
Currently uses finite differenced derivatives (partial q / partial p) and (partial R / partial p).

This will assemble the sensitivity rhs vectors to hold -(partial R / partial p_i), making them ready to solve the forward sensitivity equation.

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. 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

.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.
