Query
The Query option in Examine2D allows you to obtain analysis results along any user-defined line or polyline (e.g. plot the stress along excavation boundaries). A Query can be created in two ways:
 |
Add Query
Query Boundary
|
After a Query is created, the data can be graphed, displayed directly on the model, copied to the clipboard or exported to Excel.

Query: Add Query
With the Add Query option, you can enter a point, line or polyline, to obtain data anywhere within the rock mass. For example, in the following figure, total displacement contours are displayed, and a query has been added to show the variation of displacement with distance from the excavation boundary.
Query showing total displacement versus distance from excavation boundary
The query data corresponds to the currently selected contour data type. If the contour data is changed, the query is automatically updated to reflect the current data type. In the next figure, the contour data has been changed to Sigma 3.

Query data can also be graphed. A shortcut to create a graph, is to right-click on the query and select Graph Data from the popup menu. The graph will be immediately generated as shown in the following figure.

The number of points along the query can be user-defined when the query is created, or can be edited at a later time by right-clicking on the query and selecting Edit Locations from the popup menu.

Query: Query Boundary
The Query Boundary option allows you to automatically create a query exactly on a boundary (i.e. excavation or ground surface boundary). A convenient shortcut is to simply right-click on a boundary and select Query Boundary from the popup menu.

Boundary query created with Query Boundary option (Sigma1 contours)
Boundary queries are graphed in exactly the same way as queries created with the Add option. Note: the starting point of the query is indicated by a red dot on the model, which corresponds to the first point of the graph.

The Query Boundary option is useful for two reasons:
|
1) The query is automatically created on the entire boundary with one mouse
click, so the user does not have to manually select each segment of the
boundary.
2) The query data is obtained directly from the raw boundary element data, and
is therefore "exact", rather than interpolated from the contours near the
boundary.

Query: Export Data
Query data can easily be exported if you wish to post-process the data in other applications or include the data in reports. You can copy the data to the clipboard or export to Excel with a single mouse click.

Query: Display Options
A variety of display options are available for customizing the appearance of a query on the model. These are available in the Display Options dialog.
Query display options
For example, in the following figure, the bars representing the data magnitude are displayed on the opposite side of the boundary, with a red fill colour. The onscreen size, colour, fill pattern and other display options can be customized.
