80.2.8 Customizing display and calculation of resultant force and moment on the active view cuts

You can use the free body options for view cuts in the Visualization module to customize how the resultant force and moment displayed on the active view cut are calculated and to customize the summation point and coordinate system transformation. Abaqus/CAE can calculate the resultant force and moment by cutting through the current display group or by cutting through the whole model. Calculating these values by cutting through the current display group provides greater flexibility—for example, you can calculate the total resultant force and moment over four specific locations in your model by including them all in the display group—but Abaqus/CAE will display the resultant force and moment data only when the view cut and the display group intersect.

You can also customize the content and appearance of all free body cuts in the current viewport; see Customizing general display options for free body cuts, Section 67.5.1.

By default, Abaqus/CAE displays the resultant force and moment only once for each view cut for which you toggle on display of the resultant force and moment. If desired, you can also display a series of vectors that show the resultant force and moment data at regular intervals through the entire model or through a portion of the model.

To customize display and calculation of resultant force and moment on the active view cuts:

  1. From the main menu bar, select OptionsView Cut.

    The View Cut Options dialog box appears.

    Tip:  You can also use the view cut manager to customize the cut options. From the main menu bar, select ToolsView CutManager, and click Options in the view cut manager.

  2. Click the Free Body tab.

  3. From the Computation based on options:

    • Select Cutting through the current display group to compute the resultant force and moment based on a view cut through the current display group.

    • Select Cutting through the whole model to compute the resultant force and moment based on a view cut through the entire model.

  4. If desired, drag the Number of free bodies slider to increase or decrease the number of locations in the model for which resultant force and moment will be calculated and displayed for the selected view cut. By default, resultant force and moment are displayed only on the selected view cut.

    If you display the resultant force and moment in multiple locations for the selected view cut, you can also customize the minimum and maximum values of the line segment within which Abaqus/CAE will display the resultant forces and moments. By default, the minimum and maximum values are set to allow for distribution of vectors throughout the entire model.

  5. If desired, customize the summation point or the coordinate system transformation options for the resultant force and moment vectors arising from view cuts.

    1. From the Summation point options, select the three-dimensional location from which the resultant force and moment vectors originate.

      • Select Centroid of cut to place the summation point automatically at the centroid of the surface of the view cut.

      • Select User-defined, and specify a custom three-dimensional location in space.

    2. From the Component resolution options, you can specify the coordinate system transformation that takes place when vectors are displayed in component form. (See Customizing general display options for free body cuts, Section 67.5.1, for more information about displaying force and moment vectors in component form.)

      • Select Normal and tangential to orient the component vectors with the normal and the tangent of the surface you select.

      • Select CSYS and a coordinate system to transform the component vectors to a custom coordinate system.

      The Component resolution options affect the display of resultant forces and moments only when component vector display is selected in the Free Body Plot Options dialog box.

  6. Toggle on Show heat flow rate if available to display the heat flow rate in terms of energy per time across the view cut.

  7. If you want to customize the content and appearance of the free body cuts in the viewport—both the free body cut displayed on the active view cut and those created using the Free Body toolset—click to access the Free Body Plot Options. See Customizing general display options for free body cuts, Section 67.5.1.
