void oomph::TElement1BulkCoordinateDerivatives::faces0	(	const Vector< double > &	s,
		DenseMatrix< double > &	dsbulk_dsface,
		unsigned &	interior_direction
	)

Function for both faces – the bulk coordinate is fixed on both.

    {
      // Bulk coordinate s[0] does not vary along the face
      dsbulk_dsface(0, 0) = 0.0;
 
      // The interior direction is given by s[0]
      interior_direction = 0;
    }
