NAME

ElmMatVecCalcStd - a default version of class ElmMatVecCalc

INCLUDE

include "FEM.h"

SYNTAX

 class ElmMatVecCalcStd : public ElmMatVecCalc
 {
 public:
   Handle(ElmItgRules) integrator;
   // (need a handle since FEM::finite_elm may keep its pointer to integrator!)

   ElmMatVecCalcStd (NumItgPoints itg_points = GAUSS_POINTS,
                     int relative_order = 0);
  ~ElmMatVecCalcStd () {}

   virtual void calcElmMatVec
     (
      int            elm_no,
      ElmMatVec&     elmat,
      FiniteElement& fe,
      IntegrandCalc& integrand,
      FEM&           fem
     );

 private:
   // this one is included to avoid warning (hides virtual...)
   // to use this function, an IntegrandCalc subclass object must be
   // supplied by this class:
   virtual void calcElmMatVec
     (
      int            /*elm_no*/,
      ElmMatVec&     /*elmat*/,
      FiniteElement& /*fe*/,
      FEM&           /*fem*/
      // IntegrandCalc objects are made inside this function body
     ){}
 };

KEYWORDS

DESCRIPTION

The class offers a default implementation  of  the  calcElmMatVec
functions  that is provided by a ElmMatVecCalc functor.  In fact,
the implementation in  this  class  coressponds  to  the  default
implementation  of FEM::calcElmMatVec that many simulator classes
can make use of directly. It means that  surface  integrals  over
the sides of the elements are omitted.

See the base class for more details.
