You can create a body charge load to apply an electric charge to a body in a piezoelectric analysis.
To create or edit a body charge:
Display the body charge load editor using one of the following methods:
To create a new body charge load, follow the procedure outlined in “Creating loads,” Section 16.8.1 (Category: Electrical; Types for Selected Step: Body charge).
To edit an existing body charge load using menus or managers, see “Editing step-dependent objects,” Section 3.4.12. To edit the region to which the load is applied, see “Editing the region to which a prescribed condition is applied,” Section 16.8.4.
In the Magnitude field, enter the charge density (units CL–3).
If desired, click the arrow to the right of the Amplitude field, and select the amplitude of your choice from the list that appears. Alternatively, you can click Create to create a new amplitude. (See Chapter 38, “The Amplitude toolset,” for more information.)
Note: The amplitude field appears only if amplitudes are valid for the type of perturbation step in which you are creating the load. For more information, see “Linear perturbation analysis steps,” in “General and linear perturbation procedures,” Section 6.1.2 of the ABAQUS Analysis User's Manual.
