Vector Toolbox
The Vector toolbox controls the display of vector data.
- If the Vector toolbox is not visible, display it by clicking
the Toolbox menu and selecting Vector.
- Clicking Default will
assign default settings to the selected tab. Default settings are given in
parentheses below.
- The Subsample tab allows you to display a subset of vectors.
- The subset of vectors is defined by the minimum value (Min), maximum value (Max),
and the sampling rate for the i, j, and k indices. For example,
if Min = 3, Max = 20, and Rate = 4 for index i, then vectors will be displayed at i values
of 3, 7, 11, 15 and 19. (By default, Min, Max and Rate are set to show all vectors.)
- You may also click the up or down arrow to increase or decrease the Min or Max values.
For SUTRA models with irregular meshes, only the k rate is active and the nodes throughout the mesh will be subampled based on their node numbers.
- The Appearance tab allows you to:
- Set the Scale Factor
for the vectors. (See note 1 below.)
Check of uncheck the Log Transform option to either apply a log transformation to the ratio of the vector to the smallest vector or to use the vector magnitudes without transformation.
- Check or uncheck the Show Base option to show or hide small cubes
at the starting point of each vector.
- Check the up or down arrow to increase or decrease the size of the base cubes.
- Set the vector color to black, gray, or white.

- The Threshold tab allows you to:
- Check the Apply Threshold option to display only those vectors having magnitudes within
the threshold range.
- Uncheck the Apply Threshold option to turn off thresholding.
- Specify the minimum and maximum vector magnitudes
to define the threshold range.
- The Crop tab allows you to:
Note
- When model data are loaded, Model Viewer
computes a default scale factor based on the maximum vector magnitude
at the selected time to display data. The actual value of the
scale factor is unimportant. To lengthen the vectors, simply increase
the scale factor. To shorten the vectors, decrease scale factor.
