Description

The plot.2d statement allows the user to prepare a two dimensional xy plot. This command is usually used to look at material boundaries and grids, however, it can also be used to plot a flow field. Generally, this command is dne immediately before a [contour.html contour] command so that the isoconcentration lines are plotted in context with the structure. This command while return an error for a one-dimensional simulation.

x, y, z: For a two-dimensional simulation, these parameters are unnecessary. In three-dimensions, one of these three must be specified to indicate the cut line through the structure.
max: This command takes a list of numeric values which will be the ends of the x and y axis, respectively. The first argument is x and the second is the y value. A single value will always be interperted as the x value. The default is the maximum extent of the current structure.
min: This command takes a list of numeric values which will be the ends of the x and y axis, respectively. The first argument is x and the second is the y value. A single value will always be interperted as the x value. The default is the minimum extent of the current structure.
clear: The clear parameter specifies whether the graphics screen should be cleared before the the graph is drawn. If true, the screen is cleared. It defaults to true.
fill: The fill parameter specifies that the device should be drawn with the proper aspect ratio. If fill is false, the device will be drawn with the proper aspect ratio. When true, the device will be expanded to fill the screen. It defaults to false.
gas: This parameter specifies that the grid in the gas should also be plotted. It defaults false, so no gas grid is shown.
boundary: This parameter specifies that the device outline and material interfaces should be drawn. It defaults to false.
col.bound: Use this color to draw the boundary in. Any legal x11 color may be specified.
grid: The grid parameter specifies that the numerical grid the problem was solved on should be drawn. It defaults to false.
col.grid: Use this color to draw the grid in. Any legal x11 color may be specified.
vector: The vector parameter takes a vector field name as an argument. This indcates arrows proportional to the size of the vector and in the direction of the vector at each node. This option does not yet work for three-dimensional simulations.
vleng: The length of the vectors is scaled so that the maximum vector has length vleng, specified in microns. The default is 0.1um.
vmax: Use this as the maximum velocity instead of searching for it.

Examples

plot.2d grid

This command will draw the triangular grid and axis. Each material will plotted in a different color.

plot.2d bound min ={2 5}

This command will draw the material interfaces with the maximum x and y values of 2.0 and 5.0 um.

plot.2d bounds

This command will draw the material interfaces and place symbols at each coordinate in the mesh.

plot.2d vector=Velocity vlen=0.1 !clear

This command will plot the Velocity vector field. The maximum arrow drawn will have length of 0.1um. The plot surface will not be cleared.
