position() [1/2]

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

inlinevirtual

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

Reimplemented from oomph::GeomObject.

  {
   position(xi,r);
  }

position() [2/2]

void MyHelicalCylinder::position ( const Vector< double > &  xi, Vector< double > &  r  ) const

inlinevirtual

Lagrangian coordinate xi.

Implements oomph::GeomObject.

{
 r[0] = (1.0/Delta)*cos(xi[0]) + xi[2]*Radius*cos(xi[0])*cos(xi[1]);
 r[1] = (1.0/Delta)*sin(xi[0]) + xi[2]*Radius*sin(xi[0])*cos(xi[1]);
 r[2] = P*xi[0]/(2.0*Pi) - xi[2]*Radius*sin(xi[1]);
