Display vectors |
Menu: View results->Display Vectors
This option displays a menu with results from vectors and matrices (where the principal values have been previously evaluated by the program). From the menu of variables, choose the one you wish to see displayed; it will be shown with the default analysis and step (this can be changed with the Default Analysis/Step option in the menu). Once a result is chosen, the program will display the nodal vectors of the chosen result. The vectors that are drawn can be scaled interactively. The factor can be applied several times and every time it changes to the new input value.
You can modify the colour of the vectors, which by default are drawn in green, so that all the vectors are drawn in the same colour, or you can let the color of the vectors vary according to the result module.
When drawing a matrix result (3x3 symmetrical), such as the stress tensor, only a single color representation of principal values is available: blue when negative (also drawn as >< representing compressions), and red when positive (also drawn as <> representing tensions).
A vector will be separated into its X, Y, and Z components and its module. So either the X, Y or Z component or the whole vector (represented by the module) can be drawn. Symmetrical matrices will be unfolded into: Si component, Sii component, Siii component, and 'All' components. Any of these components can be selected to be visualized. Si, Sii and Siii represent the eigen values and vectors of the matrix results which are calculated by GiD, and which are ordered according to the eigen value.
Display vectors is supported for results defined over nodes or gauss points.
Several configuration options can be accessed via the Options menu.
Menu: Options->Vectors
Note: The above four options have no effect when viewing a matrix result or local axes.
- Point: the arrow head will be drawn as a point. The style used to draw these point like arrow heads can be modified through the point options window described before, see Point and Line options .
- Lines: the arrow head will be drawn as four lines.
- 2 Triangles: the arrow head will be drawn with two intersecting triangles.
- 4 Triangles: the arrow head will be drawn as cones of four triangles.
- 8 Triangles: the arrow head will be drawn as cones of eight triangles.
- Fixed sized: then the factor used when the vectors are displayed is the number of pixels of the vector.
- Modulus dependent: then the factor used when the vectors are displayed is the factor of magnification of the vector.
Note: This last option affects also matrix and local axes results.
