Use a query curve

For more information about the different usage options, see Applying a query curve.

Note:

To use a query curve as input to a nodal force reports on path, see Shear, moment, and torque diagrams. The query curve is defined by its vertices.

Use the vertices of the query curve, and, optionally, the vertices of intersecting edges and faces

1. Do one of the following depending on whether you are creating a graph or a result probe.In the Graph dialog box, select the Define By Query Curve check box. In the Result Probe dialog box, from the Selection Type list, select Query Curve.

2. From the Curve Name list, select a query curve. Tip: To view the entities of the query curve, select the Preview check box.

3. (Optional) To reverse the direction of the query curve, click Reverse Direction .

4. From the Curve Usage list, select one of the following:Use Vertices — Use the vertices of the query curve.Use Intersection Location — Use both the vertices of curve and the points of intersection with element edges and faces.

5. From the Resultant Curve Location list, select one of the following:Use As Is — Use the points in the query curve as is. Snap to Closest Node — Snap to the closest node for each of the points in the query curve. The nodal coordinates are replaced with coordinates of actual points. Use Intersected Elements — Use the element IDs on which each of the points lie instead of the actual points.

6. Move the Distance to Mesh Tolerance slider to the tolerance for finding the nearest point on a mesh for each vertex of the query curve, which is helpful when the segment of the query curve is not exactly on the mesh but close to it. In the box to the right, type a limit for the tolerance.The following figure shows the resulting query curve when the distance to mesh tolerance is set to 3.0.

7. If you selected Use As Is, move the Duplicate Location Tolerance slider to the tolerance for eliminating locations that are very close. In the box to the right, type a limit for the tolerance. If the locations of data points are close, increasing the tolerance merges the locations into one to produce a smaller number of data points.

8. If you selected Snap to Closest Node, move the Node Search Tolerance slider to the tolerance for searching for a node that is closest to a point on the resultant curve. In the box to the right, type a limit for the tolerance. Set the tolerance to a lower value if you want to use the nodes closest to the query curve usage location. If the tolerance is too large and multiple nodes exist within the tolerance, the software uses the closest node.

9. Set other options in the dialog box. For example, to output the results of a result probe as a 3D graph, from the Output Options list, select 3D Graph.

10. Click OK.

Use the points projected on the nearest element faces along the selected vector

The line segments of the query curve form a path on the element faces.

1. In the Graph or Result Probe dialog box, from the Selection Type list, select Query Curve, and then from the Curve Name list, select a query curve.

2. From the Curve Usage list, select Project to Element Faces.

3. Move the Distance to Mesh Tolerance slider to the tolerance for finding the nearest point on a mesh for each projected vertex of the query curve, which is helpful when the vertex does not project on the mesh but is slightly outside it. In the box to the right, type a limit for the tolerance.

4. Next to Specify Vector, select a command from the vector type menu to specify the direction along which to project the query curve on the nearest element faces or click Select Vector to use the Vector dialog box. For more information, see the Vector tool dialog box.

5. Set other options in the dialog box. For example, to output the results of a result probe as a 3D graph, from the Output Options list, select 3D Graph.

6. Click OK.
