The Boundary Mode Analysis (
) study and study step are used to compute the propagation constants or wave numbers as well as propagating mode shapes, for a given frequency at a port.
The Boundary Mode Analysis study step’s Settings window contains the following sections:
Select a method to Transform:
Effective mode index (the default),
Out-of-plane wave number, or
None. For 3D Solid Mechanics and Pressure Acoustics, Frequency Domain,
Effective mode index is not available, and
Out-of-plane wave number is the default.
Enter a Port name if applicable. The default is 1.
Enter a value or expression for the Mode analysis frequency. The default frequency depends on the physics interfaces in the study.
From the Settings list, choose
Physics controlled (the default) to use linearization point settings controlled by the physics interfaces. Choose
User defined to specify the linearization point using the
Method list. Select:
Use the Study list to specify which solution to use from the available studies. Select:
