Derive from this base class if your residual is of the form


i.e. if the test function (_grad_test[_i][_qp]) can be factored out.

Derived classes


  • precomputeQpResidual() instead of computeQpResidual() (do not multiply by _grad_test[_i][_qp]).

  • precomputeQpJacobian() instead of computeQpJacobian() (do not multiply by _grad_test[_i][_qp])

  • computeOffDiagJacobian still has to be implemented as if deriving from Kernel.

Note that precomputeQpResidual() and precomputeQpJacobian() return a RealGradient type.
