Detailed Description

///////////////////////////////////////////////////////////////////// ///////////////////////////////////////////////////////////////////// ///////////////////////////////////////////////////////////////////// Base class for penetrator. Must be able to compute the penetration with another body, based on the position vector, x, to, and the outer unit normal, n, on that other body.

equilibrium_data()

virtual Vector<std::pair<Data*,unsigned> > oomph::Penetrator::equilibrium_data ( )

inlinevirtual

Vector of pairs identifying values (via a pair of pointer to Data object and index within it) that correspond to the Data values that are determined by the horizontal/vertical/... equilibrium of force equations. Empty by default, indicating that the penetrator is in a prescribed position (i.e. a position that is not determined as part of the solution!)

Reimplemented in CircularPenetratorElement, CircularPenetratorElement, and HeatedCircularPenetratorElement.

   {
    Vector<std::pair<Data*,unsigned> > dummy;
    return dummy;
   }

output()

virtual void oomph::Penetrator::output ( std::ostream &  outfile, const unsigned &  nplot  ) const

pure virtual

Output coordinates of penetrator at nplot plot points.

Implemented in CircularPenetratorElement, CircularPenetratorElement, HeatedCircularPenetratorElement, and oomph::CircularPenetrator.

Referenced by MeltContactProblem< ELEMENT >::doc_solution(), SolarRadiationProblem< ELEMENT >::doc_solution(), and ContactProblem< ELEMENT >::doc_solution().

penetration()

virtual void oomph::Penetrator::penetration ( const Vector< double > &  x, const Vector< double > &  n, double &  d, bool &  intersection  ) const

pure virtual

Get penetration for given point x with outer unit normal n. Should return the negative distance along outer unit normal to the
closest point on the penetrator, so that minus values imply no penetration and positive ones imply penetration. If the ray from the unit normal never crosses the penetrator,set intersection to false In this case, d can be set to anything, as it should be ignored anway. Returning a bool moves the problem of deciding what to do with non-intersection to each individual method

Implemented in CircularPenetratorElement, CircularPenetratorElement, HeatedCircularPenetratorElement, and oomph::CircularPenetrator.

Referenced by oomph::SurfaceContactElementBase< ELEMENT >::penetration().

rigid_body_displacement()

virtual Vector<double> oomph::Penetrator::rigid_body_displacement ( ) const

inlinevirtual

Get rigid body displacement of reference point in penetrator. Broken virtual, so you don't really have to imlement this...

Reimplemented in HeatedCircularPenetratorElement, and oomph::CircularPenetrator.

  {
   throw OomphLibError(
    "This is a broken virtual function. Please implement/overload. ",
    OOMPH_CURRENT_FUNCTION,
    OOMPH_EXCEPTION_LOCATION);
  }

References OOMPH_CURRENT_FUNCTION, and OOMPH_EXCEPTION_LOCATION.

surface_coordinate()

virtual void oomph::Penetrator::surface_coordinate ( const Vector< double > &  x, Vector< double > &  zeta  ) const

inlinevirtual

Get surface coordinate along penetrator for given point x; implies some sort of "projection"-type relation between point x and the parametrisation of the surface (e.g. polar angle).

Reimplemented in HeatedCircularPenetratorElement, and oomph::CircularPenetrator.

  {
   throw OomphLibError(
    "This is a broken virtual function. Please implement/overload. ",
    OOMPH_CURRENT_FUNCTION,
    OOMPH_EXCEPTION_LOCATION);
  }
