You can create a body current density load to define current density over
a volume in an eddy current analysis. The body current density load is
available only in an electromagnetic model.
Display the body current density load editor using one of the
following methods:
To create a new body current density load, follow the procedure
outlined in
Creating loads
(Category:
Electrical/Magnetic; Types for
Selected Step: Body current
density).
If you selected the Uniform distribution option,
perform the following steps:
In the Component 1, Component
2, and (if applicable) Component 3 fields,
enter the real (in-phase) and imaginary (out-of-phase) parts of the body
current density vector.
Abaqus/CAE
calculates the magnitude and direction of the body current density vector.
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
to create a new amplitude. (See
The Amplitude toolset
for more information.)
Click OK to save your data and to exit the
editor.
If you selected the User-defined distribution
option, perform the following steps:
If desired, in the Component 1,
Component 2, and (if applicable) Component
3 fields enter the real (in-phase) and imaginary (out-of-phase)
parts of the body current density vector.
Abaqus/CAE
calculates the magnitude and direction of the body current density vector and
that information is passed into the user subroutine.
Click OK to save your data and to exit the
editor.
In the job editor, click the General tab, and
specify the file containing the user subroutine that defines the magnitude and
direction of the load. For more information, see
Specifying general job settings.
Note:
You can specify only one user subroutine file in the job editor;
if your analysis involves more than one user subroutine, you must combine the
user subroutines into one file and then specify that file.
