Graphic Display Specifications

Previous pageReturn to chapter overviewNext page

The MONITORS or PLOTS sections can contain one or more display specifications of the following types:

 

CONTOUR ( arg )        

Requests a two dimensional contour map of the argument, with levels at uniform intervals of the argument.

May be combined with FIELDMAP (as CONTOUR FIELDMAP) to generate overlayed potential contours and field lines.

 

CONTOUR ( arg1, arg2 )        

Requests a two dimensional contour map of both arg1 and arg2, each with levels at independent uniform intervals.

A level table is displayed for both arg1 and arg2.

 

ELEVATION ( arg1,   [arg2,...] ) path        

Requests a two dimensional display (some times called a line-out) which displays the value of its argument(s) vertically and the value of its path horizontally.  

Each ELEVATION listed must have at least one argument and may have multiple arguments separated by commas.  

path can be either a line segment specified using the forms FROM (X1,Y1) TO (X2,Y2) or ON name, where name is a literal string selecting a path named in the BOUNDARIES section.

 

FIELDMAP ( arg ) ON namedpath        

Requests a two dimensional map of the force field lines of a potential, arg.

The namedpath will be used as the starting boundary of the field lines.

The number of field lines can be adjusted using the modifier FIELDLINES.

A level table is not displayed.

May be combined with CONTOUR (as CONTOUR FIELDMAP) to generate overlayed potential contours and field lines.

See example "Samples | Applications | Electricity | Fieldmap.pde".

 

GLCONTOUR ( arg )        

Requests a three dimensional plot of the computation grid, with surface values of arg.  

Only the outer surface of the grid will be drawn.  

Standard ON qualifiers may be applied.

This plot can be interactively rotated by clicking and dragging the mouse, as well as panned using the arrow keys.

 

GLGRID ( arg1, arg2, arg3 )        

Requests a three dimensional plot of the computation grid, with nodal coordinates defined by the three arguments.  

Only the outer surface of the grid will be drawn.  

This plot can be interactively rotated by clicking and dragging the mouse, as well as panned using the arrow keys.

 

GLSURFACE ( arg )        

As regular SURFACE plot but displayed using the OpenGL graphics.

This plot can be interactively rotated by clicking and dragging the mouse, as well as panned using the arrow keys.

 

GRID ( arg1, arg2 )        

Requests a two dimensional plot of the computation grid, with nodal coordinates defined by the two arguments.  

Grids are especially useful for displaying material deformations.  

In 3D problems, a two-argument GRID plot will show a cut-plane, and must be followed by an ON specification.

3D cut plane grid plots do not necessarily accurately represent the computational grid.        

 

GRID ( arg1, arg2, arg3 )        

Requests a three dimensional plot of the computation grid, with nodal coordinates defined by the three arguments.  

Only the outer surface of the grid will be drawn.  

This plot can be interactively rotated by right-clicking and selecting the "Rotate" menu entry.

 

MODE_SUMMARY

In eigenvalue problems, this produces a SUMMARY page for each mode (comparable to the version 5 SUMMARY).

This has been replaced with MODE SUMMARY (no underscore).

 

SUMMARY        

This plot type defines a text page on which only REPORT items may appear.  

A SUMMARY page can be EXPORTed to produce text reports of scalar values.        

 

SUMMARY ( 'string' )        

If a string argument is given with a SUMMARY command, it will appear as a page header on the summary page.

 

SURFACE ( arg )        

A quasi three dimensional surface which displays its argument vertically.  

If no VIEWPOINT clause is used, the viewing azimuth defaults to 216 degrees, the distance to three times the size, and the viewing elevation to 30 degrees.

This plot can be interactively rotated by right-clicking and selecting the "Rotate" menu entry.

VECTOR ( vector )        

Requests a two dimensional display of directed arrows in which the direction and magnitude of the arrows is set by the vector argument.  

The origin of each arrow is placed at its reference point.        

 

VECTOR ( arg1, arg2 )        

Requests a two dimensional display of directed arrows in which the horizontal and vertical components of the arrows are given by arg1 and arg2.

The origin of each arrow is placed at its reference point.

For all commands, the argument(s) can be any valid expression.
