Detailed Description

This class is part of the rbOOmit framework.

TransientRBConstruction extends RBConstruction to add functionality relevant in the time-dependent case.

We can handle time controls on the RHS as h(t)*f(x, $ \mu $). See Martin Grepl's thesis for more details.

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.

◆ add_vector()

)
inherited

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

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).

void libMesh::LinearImplicitSystem::attach_shell_matrix ( ShellMatrix< Number > *  shell_matrix)
inherited

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 argument.

◆ compute_Fq_representor_innerprods()

virtual void libMesh::RBConstruction::compute_Fq_representor_innerprods ( bool  compute_inner_products = true)
protectedvirtualinherited

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.

◆ compute_max_error_bound()
