Member Function Documentation

◆ data_values_of_field()

virtual Vector<std::pair<Data*, unsigned> > oomph::ProjectableElementBase::data_values_of_field ( const unsigned & fld )

pure virtual

Pure virtual function in which the element writer must specify the values associated with field fld. The information is returned in a vector of pairs which comprise the Data object and the value within it, that correspond to field fld. E.g. in Taylor Hood elements the fld-th velocities are stored at the fld-th value of the nodes; the pressures (the DIM-th field) are the DIM-th values at the vertex nodes etc.

◆ get_field()

virtual double oomph::ProjectableElementBase::get_field	(	const unsigned &	time,
		const unsigned &	fld,
		const Vector< double > &	s
	)

pure virtual

Return the fld-th field at local coordinates s at time-level time (time=0: current value; time>0: history values)

◆ jacobian_and_shape_of_field()

virtual double oomph::ProjectableElementBase::jacobian_and_shape_of_field	(	const unsigned &	fld,
		const Vector< double > &	s,

	)

pure virtual

Return Jacobian of mapping and the shape functions associated with field fld. The number of shape functions must match the number of values specified in nvalue_of_field(...). For Lagrange-type interpolations the shape functinos are simply the "normal" nodal shape functions; if the element contains internal Data that is not associated with shape functions, simply set the corresonding shape function to 1.
