Query curves

You can use a query curve, which is a composite curve, as input to 2D and 3D graphs, nodal force reports on path, or to specify where you want results reported in a result probe. You can report results on an array of locations along the query curve by specifying usage options. The following shows query curves used as input to a 3D graph and a result probe.

Creating and using query curves

You can create a query curve in pre-processing using polygon geometry or FE entities or post-processing using results data. To create a query curve, you can select existing curves or create curves using points, mesh points, nodes, or polygon edges. In pre-processing, smart selection helps you make selections. In post-processing, you can select nodes in the model or coordinate positions in the native results coordinate system.

Query curve created in pre-processing

After you create the query curve, you can use it as input to a result probe or graph. When you use it as input, you select usage options that specify:

• How to extract points along the query curve. For example, you can use the vertices of individual segments of the query curve, use all the points where the curve intersects the mesh, or project the curve on the mesh in a specified direction.

• The desired result location for the points. For example, the locations can be interpolated results on the points of the query curve, the results on nodes closest to the points, or results on the elements containing those points.

Managing and editing query curves

Query curves are saved in the Simulation file. They appear in the Post Processing Navigator. They do not appear in the graphics window until you use them as input.

The Query Curve Manager lets you create, edit, and delete query curves. You can also select a query curve and see it displayed in the graphics window.
