◆ position() [1/2]

void oomph::SimpleCircle::position	(	const unsigned &	t,
		const Vector< double > &	zeta,
		Vector< double > &	r
	)		const

inlinevirtual

Position Vector at Lagrangian coordinate zeta at time level t (t=0: present; t>0: previous level). Steady object, so we simply forward the call to the steady version.

Reimplemented from oomph::GeomObject.

64 {position(zeta,r);}

oomph::SimpleCircle::position
