 ### Task 5: Implement your own local residual
 <hr>
 
-Most types in DuMuX are properties that can be changed just like the material law. In the following task we implement our own 2p2c local residual, i.e. the class that computes the element residual  in every Newton step. The file `mylocalresidual.hh` contains a copy of the original local residual class used for the 2p2c model renamed to `template<class TypeTag> class MyTwoPTwoCLocalResidual`.
