In-Code documentation of "adjustSolution" function

Is it possible to add a comment for adjustSolution() in the header.

 /**
  * @see FiniteVolumesSolver
  */
 void adjustSolution(const double* const x,const double t,const double dt, double* Q) override;

Also is there any advise on how to get the corner points of the cell. I guess there was a adjustPointSolution() in the past but not anymore.
