* Assessed object: Possible choices in case of a specified system: Solution, Residual, RecalcResidual. For specified post-operations this has to be omitted. Residual and RecalcResidual can only be used for Newton's method. Residual assesses the residual from the last iteration whereas RecalcResidual calculates the residual once again after each iteration. This means that with Residual usually one extra iteration is performed, but RecalcResidual causes higher computational effort per iteration.

* Error norm: Type of the error norm. Possible choices are: L1Norm, MeanL1Norm, L2Norm, MeanL2Norm, LinfNorm (→ see definitions below).

Here a complete example is given for a electro-thermal problem. We have an object consisting of two materials. On top a uniform current source is applied. The dissipated power is heating the body. The bottom of the body is kept at a fix temperature. The electrical conductivity is temperature dependent.
