This functionality allows to view the attributes of elements (meshes, cells, points, gauss points) displayed in the viewer
By default the indication of position and size of the selected object is always present in the top left corner of the viewer.
To access more advanced selection possibilities the Main menu choose View - > Windows -> Selection, choose the necessary type of elements (Actor, Cell, Point or Gauss Point) in the dialog box and click on the element of the required type in the viewer. The chosen element will be highlighted and its attributes will be displayed in the dialog box.
An Actor (any 3D object (presentation of a submesh, field presentation) displayed in the viewer) possesses the following characteristics:
-
Mesh name - name of the mesh on which the presentation is built.
-
Field name - name of the mesh on which the presentation is built.
-
Position - coordinates of the object in 3d space.
-
Size of the object (expressed as the extent along the coordinates).
The following information about Cells is available:
-
Mesh name - name of the mesh on which the presentation is built.
-
Field name - name of the mesh on which the presentation is built.
-
ID - number of the cell.
-
Scalar Value applied to the cell (if any).
-
Vector Value applied to the cell (if any).
-
Attributes of the points forming this cell (in table layout).
You can get the following information about Points:
-
Mesh name - name of the mesh on which the presentation is built.
-
Field name - name of the mesh on which the presentation is built.
-
ID Number of the point.
-
Scalar Value applied to the point (if any).
-
Vector Value applied to the point (if any).
-
Coordinates (x,y,z) of the point in 3d space.
-
Indexes (i,j,k) of the point (for structured meshes only).
-
Scalar and Vector values assigned to the point (if any).
- Note:
- It is possible to examine the attributes of a definite point or cell, selected by its ID number. For that, input the ID number of a definite point or cell in the ID field, the attributes of this point or cell will be immediately displayed.
Gauss points can be selected with the help of a special cursor with markers (pyramids). The cursor is dynamically generated so that the apexes of each pyramid touch the point sprite boundary, and the height of the pyramid is fixed.
Once a point is selected, the presentation is centered around it. In the picture the already selected point is surrounded with yellow markers and the point touched by the cursor is surrounded with red markers.
In addition, the active scalar bar is updated to highlight the corresponding value of the selected scalar value by a black line.
The following information is displayed in the dialog box:
-
Mesh name - name of the mesh on which the presentation is built.
-
Field name - name of the mesh on which the presentation is built.
-
Parent ID - ID of the point within its parent mesh element.
-
Local ID of the Gauss point.
-
Display parent mesh element - allows to visualize or hide the parent mesh element of the selected gauss point.
Find group and Selection Preferences button are common for all types of selectable objects.
Here, it is possible to choose the mathematical formula, input values to limit the range of the selection and apply them with the checkmark button. Then the required element can be chosen from the list of elements fitting in the defined range.
Selection Preferences button allows to customize selection preferences.
-
Cursor - allows to adjust the Size of the cursor (ranging from 0.1 to 1), the Height of the pyramids (ranging from 0 to 10) and the Selection cursor color. This control is relevant only for the selection of Gauss points.
-
Tolerance - defines at which distance of the cursor from the point it becomes selected (ranges from 0.001 to 10).
-
Information window - allows to define the Transparency (from 0% = opaque to 100% = transparent) and Position of the window, which can be:
-
Centered below the point, or
-
located at Top-left corner of the 3D view
-
Movement of the Camera can also be defined by the user.
-
Zoom factor - This value is used to define the focal distance at the first selected point (at the end of the movement of the camera). This value is a ratio that will be multiplied by the current zoom value.
-
Number of steps - defines the smoothness of camera movement at selection by the number of iterations between two positions. If set to 1 the camera is zoomed and centered at the point momentarily. Greater numbers mean very slow camera movement.
