Constructor.
Definition at line 148 of file grid_out.cc.
GridOutFlags::Gnuplot::Gnuplot  (  const Gnuplot &  flags  ) 
Copy constructor. Needed since this class (for backwards compatibility) has a reference member variable.
Definition at line 162 of file grid_out.cc.
Copy operator. Needed since this class (for backwards compatibility) has a reference member variable.
Definition at line 172 of file grid_out.cc.

static 
Declare parameters in ParameterHandler.
Definition at line 185 of file grid_out.cc.
void GridOutFlags::Gnuplot::parse_parameters  (  ParameterHandler &  param  ) 
Parse parameters of ParameterHandler.
Definition at line 193 of file grid_out.cc.
bool GridOutFlags::Gnuplot::write_cell_numbers 
Write the number of each cell into the output file before starting with the lines it is composed of, as a comment. This might be useful if you want to find out details about the grid, for example the position of cells of which you know the number. It enlarges the size of the output significantly, however.
Default: false
.
Definition at line 245 of file grid_out.h.
unsigned int GridOutFlags::Gnuplot::n_extra_curved_line_points 
Number of points, excluding the vertices, to plot on curved lines. Since GNUPLOT can only plot straight lines, setting this number to a value greater than zero (4 or 5 is usually enough for refined grids) makes the plot look curved even though it is not.
Definition at line 253 of file grid_out.h.
unsigned int& GridOutFlags::Gnuplot::n_boundary_face_points 
Based on the vertices of the face and n_boundary_face_points additional points a tensor product mesh (transformed to the real space) of (n_boundary_face_points+2)^{dim1} points is plotted on each boundary face.
Definition at line 265 of file grid_out.h.
bool GridOutFlags::Gnuplot::curved_inner_cells 
Boolean indicating whether or not interior lines should be plotted with n_extra_curved_line_points
line segments.
Definition at line 271 of file grid_out.h.
bool GridOutFlags::Gnuplot::write_additional_boundary_lines 
Flag. If true then, when writing spacedim = 3
output, write 2*n_extra_curved_line_points
extra lines on boundary faces.
Setting this option has no effect when spacedim = 2
since, in that case, boundary faces are lines and outputting additional lines does not make sense.
dim = 2
case. For backwards compatibility, however, this will not raise a runtime error. Definition at line 284 of file grid_out.h.
