14.10 Streamline Plot
Streamlines are useful for visualing fluid flows. The streamlines are calculated by integrating a vector field at particular seed points. The seed points are determined automatically based on the vector field. Everywhere the flow enters the mesh, a seed point is placed at the center of the corresponding facet.
- Data field: selects the data field that will be used for the streamline plot.
- Color map: sets the color map used for coloring the glyphs.
- Allow Clipping: Allows the plot to be clipped by cutting planes or not.
- Step size: Sets the integration step size. A smaller value will produce more accurate flows, at the cost of a large computational expense.
- Density: Sets the density of streamlines. When this value is less than one, streamlines are seeded on random facets, selected based on this density value.
- Velocity threshold: The minimum value for the velocity for seeding.
- Range type: Sets how the range of the corresponding colormap is determined.
- Rande divisions: Sets the number of intervals for the colormap (and associated legend)
- User Range min: The minimum value for the range when the range type is set to user.
- User Range man: The maximum value for the range when the range type is set to user.
