Member Function Documentation

ngeom_data()

unsigned Flag_definition::BottomOfFlag::ngeom_data ( ) const

inlinevirtual

Number of geometric Data in GeomObject: None.

Reimplemented from oomph::GeomObject.

{return 0;} 

position() [1/2]

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

inlinevirtual

Return the position along the bottom of the flag (xi[0] varies between 0 and Lx)

Reimplemented from oomph::GeomObject.
