Method for partially assembled gradient action.
All arguments are E-vectors. This method can be called only after the method AssembleGradPA() has been called.
| [in] | x | The gradient Operator is applied to the Vector x. |
| [in,out] | y | The result Vector: \( y += G x \). |

overridevirtual |
Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.
This method can be called only after the method AssembleMF() has been called.

Prepare the integrator for partial assembly (PA) gradient evaluations on the given FE space fes at the state x.
The result of the partial assembly is stored internally so that it can be used later in the methods AddMultGradPA() and AssembleGradDiagonalPA(). The state Vector x is an E-vector.

Subclasses should override to choose a default integration rule.
This method is intended to be overridden by subclasses to choose an appropriate integration rule based on the finite element spaces and/or element transformation. The trial_fe and test_fe should be equal for linear forms. The default base-class implementation returns null, which assumes that an appropriate rule is provided by another means, or that null integration rules are handled appropriately by the caller.
