Detailed Description

Computes data to be visualized for a single element (e.g. edge positions, non-conserved variables, values at uniformly-spaced sample points) without knowing anything about the choice of visualization software.

◆ compute_contour()

Vis_data::Contour hexed::Vis_data::compute_contour	(	double	value,
		int	n_div = 10,
		int	n_newton = 4,

interpolate function to n_sample + 1 uniformly spaced points along element edges

◆ interior()

Eigen::VectorXd hexed::Vis_data::interior ( int n_sample = 21 )

interpolate function to a uniformly-spaced block of sample points n_sample on a side

◆ qpoints()

const Eigen::VectorXd & hexed::Vis_data::qpoints ( )

inline

return function evaluated at quadrature points.

◆ sample()
