GfsAdaptError uses an a posteriori error estimate of a given field as a cost function for adaptation. The error is estimated by computing the norm of the Hessian matrix of the given field, estimated using third-order-accurate discretisation operators.

The syntax in parameter files is:

[ GfsAdaptGradient ]

The cmax value of the corresponding GfsAdapt is the maximum acceptable estimated error.
