Set up and generate nodal force reports on path

1. Before you solve the model, make sure the Structural Output Request modeling object for your solution includes the results that you intend to use for the nodal force reports on path.

2. Make the Simulation file the work part.

3. Make the appropriate solution active and load the results. The software calculates the nodal force reports on path based on the results from that solution.Tip: In the Simulation Navigator, right-click the Results node and choose Open.

4. Right-click the active solution and choose Nodal Force Reports on Path.

5. From the Forces Type list, select the type of force to be diagrammed.

6. If you selected Grid Point in the previous step, do one of the following in the Elements group to select the elements to include in the calculation:To include all elements, select the All Elements check box. To select entities, click Select Object and select the entities in the main graphics window. You can also type the element IDs in the Labels box and click Select . You can type IDs one at a time, or as a space-delimited list.To select elements in a group, select the Select Groups check box. Select a group from the list or create a new group.

7. For all types of forces, to select the nodes on which the forces are calculated, do one of the following in the Nodes group:To include all nodes, select the All Nodes check box. Note: Even when you select to include all nodes using this check box, the only nodes included in the nodal force reports on path are those at each of the vertices of a query curve and a Z-direction tolerance. All nodes within the tolerance are included in the nodal force reports on path. To select entities, click Select Object .Tip: To help make selections, on the Top Border bar, from the Type Filter list, select the appropriate selection criteria. For example, to create a nodal force reports on path along the edge of a piston rod, select Polygon Edge.To select nodes in a group, select the Select Groups check box. Select a group from the list or create a new group.

8. Select a query curve that defines the set of free-body points:From the Curve Name list, select a query curve or click New Query Curve to create a new query curve.Tip: To view the entities of the query curve, select the Preview check box. (Optional) To reverse the direction of the query curve, click Reverse Direction .

9. From the CSYS list, select the coordinate system in which the software should report the nodal force calculations. The CSYS is transformed along the query curve so the X axis is constant and the Z axis is aligned with the curve's tangent as shown below. For a Cartesian, cylindrical, or spherical coordinate system, click CSYS Dialog to specify a coordinate system.

10. In the Z Tolerance box, type a Z-direction tolerance within which to include nodes.For grid point force, the software includes all nodes in the +Z and -Z directions of the specified tolerance within the plane of influence. For all other forces, such as applied or reaction, the software includes all nodes in the +Z and -Z directions of the specified tolerance. Note: The local Z-direction is for a particular integration point on the query curve that is tangent to that point. The Z tolerance is, therefore, the neighborhood defined in that direction.

11. Click OK.The software creates a nodal force reports on path for each vertex in the query curve. It displays them under the Nodal Force Reports node of the Simulation Navigator. It names them based on the prefix NFR, the name of the query curve, the type of force, and the vertex number.
