   .. py:method:: initialize()

      
      Initialize the element.

      Initialization of terms that cannot be initialized before other elements or
      the aquifer is defined.

      As we don't want to require a certain order of entering elements, these terms
      are initialized when Model.solve is called The initialization class needs to be
      overloaded by all derived classes
