stream option=value [,option=value, ...]
A plot option for the stream plot. See table below.
A value associated with the matching option . See table below.
A scaled error value. An error of 0.01 means that variations on the order of 1/100 the size of the mesh are filtered out through line reduction. 0.0 means that no variations are filtered. |
|||
The stream density. This is a scaled parameter. It relates to the "seed point density per unit area", however it is scaled such that a density of 1 results in approximately 200 streams. This is so the results are the same whether the mesh is defined in cm, mm, or any other scale. |
|||
Line color. Color Names A color index may be used in place of a color name. |
|||
Line style. Line Styles |
|||
Number to indicate thickness. 1 is the most thin, and 4 is the thickest. |
|||
Integration method for computing streams. |
|||
Integration step size. This parameter is scaled according to the size of the mesh compared to the magnitudes of the vectors to allow the step size to give similar quality results in a wide variety of meshes. If using an adaptive method, the specified step is used only as an initial value and will be adjusted according to the curvature of the flow at each point. |
|||
Name of the vector variable. The variable defines pseudocoloring as well. A 3d vector in a 2D mesh is interpreted as {x_component, y_component, colorvar}. |
Streams work in 2D and 3D meshes. Streams (or streamlines) are curves in a vector field which are tangent to the flow (instantaneous flow). They are generated from a starting "seed" point, and are propagated through a vector field via various methods.
Streams are implemented for all mesh types except non-colinear (curvilinear) 3D. For unstructured meshes, only hexahedral zones are supported at this time.
The stream command is similar to the ribbon command, except that it generates lines (streamlines) while ribbon generates a ribbon (or tube), which is the aggregate of two (or more) streamlines.
