You can create a surface current density load to define current density
over a surface in an eddy current analysis. The surface current density load is
available only in an electromagnetic model.
Display the surface current density load editor using one of the
following methods:
To create a new surface current density load, follow the procedure
outlined in
Creating loads
(Category:
Electrical/Magnetic; Types for
Selected Step: Surface 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 surface
current density vector.
Abaqus/CAE
calculates the magnitude and direction of the surface 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 surface current density vector.
Abaqus/CAE
calculates the magnitude and direction of the surface 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.
