Member Function Documentation

position() [1/2]

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

inlinevirtual

Position vector, r, to the point on the circle identified by
its 1D Lagrangian coordinate, xi (passed as a 1D Vector) at discrete time level t (t=0: present; t>0: previous). The shape of the object is not time-dependent, therefore we forward this call to the steady version.

Reimplemented from oomph::GeomObject.

  {
   position(xi,r);
  }

References UniformPSDSelfTest::r.

position() [2/2]

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

inlinevirtual

Position vector, r, to the point on the circle identified by
its 1D Lagrangian coordinate, xi (passed as a 1D Vector):

Implements oomph::GeomObject.

  {
   // Eulerian position vector
   r[0] = cos(xi[0]);
   r[1] = sin(xi[0]);
  }
