Exercise The following exercise is an example of how post-processing complex results in HyperView is done. The model used in this exercise has four load cases. The first load case contains the static result. The second load case resets the model to an unloaded structure and is the base state used for load case 3 where the eigenfrequencies are extracted. In load case 4, the response of the mass element (element ID 999) on top of the clip due to a dynamic excitation (frequency dependent load) of the bearing in a node (node id 10000) is analyzed. The model is fixed in all six degrees of freedom at node 9999.

Note that the discontinuities around the node no longer exist, and you now are able to view the contour as bands. Simple averaging means that tensor and vector components are extracted and the invariants are computed prior to averaging. In this example, the vonMises is computed at the corner of each element for the layer Z1 and then is averaged to the nodes. For additional information - see the Simple averaging topic (located in the HyperView User's Guide). 3.

Advanced averaging means that tensor (or vector) results are transformed into a consistent system, and then each component is averaged separately to obtain an average tensor (or vector). In this example, the stress components xx, yy, zz, xy, yz, xz are computed at the corners and then averaged to the nodes. From this averaged value, the invariants (like vonMises) are computed.

3. Repeat steps 1 - 3 by selecting Subcase 4 - solver_LSP instead of HyperView_LSP. Subcase 4 - solver_LSP contains results from the analysis. This subcase was set up as a combination of the loads applied in Subcase 1, Subcase 2, and Subcase 3 according to the following linear superposition equation: Subcase 4 = -0.22 *(Subcase 1) + 1.37 *(Subcase 2) + 0.55 *(Subcase 3) Notice that neither the contour nor the min and max values in the legend changed when switching between Subcase 4 - solver LSP and HyperView_LSP. This shows that HyperView calculated the same results in the linear superposition HyperView_LSP loadstep as given by the solver. Note

Step 3: Align a video using multiple point alignment or by entering camera properties. 1.

From the Image Plane panel, click on the Alignment sub-tab. This sub-tab allows you to pick points on the image (in the image plane tab) and corresponding nodes on the model (in the graphics window).

The points on the image and the corresponding nodes on the model should be as close and accurate as possible, in order to optimize the alignment and scaling. A minimum of seven points/nodes are required, however for this exercise we will select a total of nine points/nodes. Note

To enable the easy picking of nodes on the model, please make the image in the graphics window completely transparent by using the slider bar in the Display Options tab (sliding to High), or turn off the display of the Image plane from the Results browser tab. You can also adjust the color of the model, if necessary.

A set of nine node-point pairs that provided a good alignment with a very low error value are shown in the images below. For the purpose of this exercise, please try and select your points and nodes as closely as possible to those on the images:

Image plane with 9 points selected

Model with 9 nodes selected

− Select the middle of the front wheel as the first point on the image (Pixel: 184 172). − Next, select the middle of the front wheel as the first node on the model (Node: #2345791).

An Error measurement is displayed above the Align button as soon as the seventh point/node pair is picked. This measurement will then be updated as additional pairs are added. An increase in the error measurement indicates that the last pair that was picked is not ideal and it is recommended that a different pair be selected instead. Note

3.

It is recommended that you select two points which lie on different depth levels. More points at different depths will create better alignment. Also, points located at the center area of the image/video are generally preferred than points near boundaries. Incremental adjustments to orientation can be performed with the help of graphical manipulators.

Click the Align button to scale and align the model and image plane. Note

If the currently selected points have an error value greater than 75, an error message will display and will ask if you would still like to proceed. See the Alignment section of the 2D Image Planes topic for additional information.

A new view is created in the Views entity folder in the Result browser named ImagePlane1 Model1. 4.

For the purposes of better visibility and analyzing correlation, a few things can also be considered: − Adjust the transparency of the image plane using the Display Options tab. − Control the display order of the image planes and model using the Z-Stack tab. See the Z-Stack section of the 2D Image Planes topic for additional information. − Apply a filter to the image using the Filter tab. See the Filter section of the 2D Image Planes topic for additional information.

5.

An alternate method for achieving alignment is also available. Go to the Results browser tab and click on the ImagePlane Model1 view. The Entity Editor is displayed at the bottom of the browser. You can use the Entity Editor to enter or modify the camera properties in the view. See the Views section of the Entity Editor topic for additional information.
