This class provides a means to output a triangulation to a file in different formats. See the enum GridOut::OutputFormat for a list of formats and the corresponding output function names.
Usage is simple: either you use the direct form
if you know which format you want to have, or if you want the format to be a runtime parameter, you can write
The function get_output_format_names()
provides a list of possible names of output formats in a string that is understandable by the ParameterHandler class.
Note that here, we have created an unnamed object of type GridOut and called one of its write_*
functions. This looks like as if the respective function could really be made static
. This was not done in order to allow for parameters to be passed to the different output functions in a way compatible with the scheme of allowing the right output format to be selected at runtime through the generic write
function.
In order to explain this, consider each function had one or more additional parameters giving the details of output, for example position of the spectator for 3d meshed, line thicknesses, etc. While this would allow each output function any flexibility it needs, it would not allow us to use the generic function write
which is given a parameter determining the output format, since it is impractical to give it a list of parameters for each and every output format supported which it may then pass on to the respective output function.
Rather, we have chosen to let each object of this class GridOut have a set of parameters for each supported output format. These are collected in structures GridOutFlags::Eps(), GridOutFlags::Gnuplot(), etc declared in the GridOutFlags namespace, and you can set your preferred flags like this:
The respective output function then use the soset flags. By default, they are set to reasonable values as described above and in the documentation of the different flags structures. Resetting the flags can be done by calling grid_out.set_flags (GridOutFlags::Ucd());
, since the default constructor of each of the flags structures sets the parameters to their initial values.
The advantage of this approach is that it is possible to change the flags of one or more output formats according to your needs and later use the generic write
function; the actual output function then called will use the flags as set before.
Note that some of the structures describing the flags of the different output formats are empty since the respective format does not support any flags. The structure and the set_flags
function are provided anyway. Note also that some of the structures may differ between the dimensions supported by this class; they then have a template parameter, as usual.

GridOut::GridOut  (  ) 
Constructor.
Definition at line 399 of file grid_out.cc.
void GridOut::write_dx  (  const Triangulation< dim, spacedim > &  tria, 
std::ostream &  out  
)  const 
Write triangulation in OpenDX format.
Cells or faces are written together with their level and their material id or boundary indicator, resp.
Not implemented for the codimension one case.
Definition at line 709 of file grid_out.cc.
void GridOut::write_gnuplot  (  const Triangulation< dim, spacedim > &  tria, 
std::ostream &  out,  
const Mapping< dim, spacedim > *  mapping = 0 

)  const 
Write the triangulation in the gnuplot format.
In GNUPLOT format, each cell is written as a sequence of its confining lines. Apart from the coordinates of the line's end points, the level and the material of the cell are appended to each line of output. Therefore, if you let GNUPLOT draw a 2d grid as a 3d plot, you will see more refined cells being raised against cells with less refinement. Also, if you draw a cut through a 3d grid, you can extrude the refinement level in the direction orthogonal to the cut plane. The same can be done with the material id, which is plotted after the level.
A more useful application of this feature is the following: if you use the GNUPLOT command (for a 2d grid here)
* splot [:][:][2.5:3.5] "grid_file.gnuplot" * *
then the whole x and yrange will be plotted, i.e. the whole grid, but only those lines with a zvalue between 2.5 and 3.5. Since the zvalues were chosen to be the level to which a cell belongs, this results in a plot of those cells only that belong to level 3 in this example. This way, it is easy to produce plots of the different levels of grid.
mapping
is a pointer to a mapping used for the transformation of cells at the boundary. If zero, then use standard Q1 mapping.
Names and values of additional flags controlling the output can be found in the documentation of the GridOutFlags::Gnuplot() class.
Not implemented for the codimension one case.
Definition at line 3344 of file grid_out.cc.
void GridOut::write_msh  (  const Triangulation< dim, spacedim > &  tria, 
std::ostream &  out  
)  const 
Write the triangulation in the msh format.
Msh is the format used by Gmsh and it is described in the gmsh user's guide. Besides the usual output of the grid only, you can decide through additional flags (see below, and the documentation of the GridOutFlags::Msh() class) whether boundary faces with nonzero boundary indicator shall be written to the file explicitly. This is useful, if you want to reread the grid later on, since deal.II
sets the boundary indicator to zero by default; therefore, to obtain the same triangulation as before, you have to specify faces with differing boundary indicators explicitly, which is done by this flag.
Names and values of further flags controlling the output can be found in the documentation of the GridOut::Msh() class.
Works also in the codimension one case.
Definition at line 942 of file grid_out.cc.
void GridOut::write_ucd  (  const Triangulation< dim, spacedim > &  tria, 
std::ostream &  out  
)  const 
Write the triangulation in the ucd format.
UCD (unstructured cell data) is the format used by AVS and some other programs. It is described in the AVS developer's guide. Besides the usual output of the grid only, you can decide through additional flags (see below, and the documentation of the GridOutFlags::Ucd() class) whether boundary faces with nonzero boundary indicator shall be written to the file explicitly. This is useful, if you want to reread the grid later on, since deal.II
sets the boundary indicator to zero by default; therefore, to obtain the same triangulation as before, you have to specify faces with differing boundary indicators explicitly, which is done by this flag.
Names and values of further flags controlling the output can be found in the documentation of the GridOut::Ucd() class.
Works also for the codimension one case.
Definition at line 1085 of file grid_out.cc.
void GridOut::write_eps  (  const Triangulation< dim, spacedim > &  tria, 
std::ostream &  out,  
const Mapping< dim, spacedim > *  mapping = 0 

)  const 
Write the triangulation in the encapsulated postscript format.
In this format, each line of the triangulation is written separately. We scale the picture such that either xvalues or yvalues range between zero and a fixed size. The other axis is scaled by the same factor. Which axis is taken to compute the scale and the size of the box it shall fit into is determined by the output flags (see below, and the documentation of the GridOutFlags::Eps() class).
The bounding box is close to the triangulation on all four sides, without an extra frame. The line width is chosen to be 0.5 by default, but can be changed. The line width is to be compared with the extension of the picture, of which the default is 300.
The flag color_lines_on_user_flag
allows to draw lines with the user_flag
set to be drawn in red. The colors black and red are defined as b
and r
in the preamble of the output file and can be changed there according to need.
mapping
is a pointer to a mapping used for the transformation of cells at the boundary. If zero, then use standard Q1 mapping.
Names and values of additional flags controlling the output can be found in the documentation of the GridOutFlags::Eps() class. Especially the viewpoint for three dimensional grids is of importance here.
Not implemented for the codimension one case.
Definition at line 3868 of file grid_out.cc.
void GridOut::write_xfig  (  const Triangulation< dim, spacedim > &  tria, 
std::ostream &  out,  
const Mapping< dim, spacedim > *  mapping = 0 

)  const 
Write twodimensional XFigfile.
This function writes all grid cells as polygons and optionally boundary lines. Several parameters can be adjusted by the XFigFlags control object.
If levels are coded to depth, the complete grid hierarchy is plotted with fine cells before their parents. This way, levels can be switched on and off in xfig by selecting levels.
Polygons are either at depth 900level or at 900+material_id
, depending on the flag level_depth
. Accordingly, boundary edges are at depth 800level or at 800+boundary_id
. Therefore, boundary edges are alway in front of cells.
Not implemented for the codimension one case.
Definition at line 1208 of file grid_out.cc.
void GridOut::write_svg  (  const Triangulation< 2, 2 > &  tria, 
std::ostream &  out  
)  const 
Write the triangulation in the SVG format.
SVG (Scalable Vector Graphics) is an XMLbased vector image format developed and maintained by the World Wide Web Consortium (W3C). This function conforms to the latest specification SVG 1.1, released on August 16, 2011.
The cells of the triangulation are written as polygons with additional lines at the boundary of the triangulation. A coloring of the cells is further possible in order to visualize a certain property of the cells such as their level or material id. A colorbar can be drawn to encode the chosen coloring. Moreover, a cell label can be added, showing level index, etc.
Definition at line 1416 of file grid_out.cc.
void GridOut::write_svg  (  const Triangulation< dim, spacedim > &  tria, 
std::ostream &  out  
)  const 
Declaration of the same function as above for all other dimensions and space dimensions. This function is not currently implemented and is only declared to exist to support dimension independent programming.
Definition at line 1409 of file grid_out.cc.
void GridOut::write_mathgl  (  const Triangulation< dim, spacedim > &  tria, 
std::ostream &  out  
)  const 
Write triangulation in MathGL script format. To interpret this file a version of MathGL>=2.0.0 is required.
To get a handle on the resultant MathGL script within a graphical environment an interpreter is needed. A suggestion to start with is mglview
, which is bundled with MathGL. mglview
can interpret and display smalltomedium MathGL scripts in a graphical window and enables conversion to other formats such as EPS, PNG, JPG, SVG, as well as view/display animations. Some minor editing, such as modifying the lighting or alpha channels, can also be done.

Return the number of lines in the triangulation which have a boundary indicator not equal to zero. Only these lines are explicitly printed in the write_*
functions; all lines with indicator numbers::internal_face_boundary_id are interior ones and an indicator with value zero for faces at the boundary are considered default.
This function always returns an empty list in one and two dimensions.
The reason for this function is the same as for write_ucd_faces(). See there for more information.
