  GeomObject(1,2), Centre_y(centre_y), Radius(radius) { }

Member Function Documentation

geom_data_pt()

Data* GeneralCircle::geom_data_pt ( const unsigned &  j )

inlinevirtual

Return pointer to the j-th (only) Data item that the object's shape depends on.

Reimplemented from oomph::GeomObject.

  {return 0;}

interpolated_history()

bool GeneralCircle::interpolated_history ( const unsigned &  t )

inline

  {
   if(t==0) {return true;}
   else {return false;}
  }

References plotPSD::t.

ngeom_data()

unsigned GeneralCircle::ngeom_data ( ) const

inlinevirtual

How many items of Data does the shape of the object depend on? This is implemented as a broken virtual function. You must overload this for GeomObjects that contain geometric Data, i.e. GeomObjects whose shape depends on Data that may contain unknowns in the overall Problem.

Reimplemented from oomph::GeomObject.

{return 0;}

position() [1/4]

void GeneralCircle::position ( const unsigned &  t, const Vector< double > &  xi, Vector< double > &  r  ) const

inlinevirtual

Return the position of the circle as a function of time (doesn't move as a function of time)

Reimplemented from oomph::GeomObject.

  {
   position(xi,r);
  }

position() [2/4]

void GeneralCircle::position ( const unsigned &  t, const Vector< double > &  xi, Vector< double > &  r  ) const

Return the position of the circle as a function of time (doesn't move as a function of time)

Reimplemented from oomph::GeomObject.
