The default birefringence results show stress-optical effects for light coming from one of two global axial directions (+Z, -Z) and for light of a fixed wavelength (546.1 nm).
If these choices are inadequate (for instance, your model is oriented so that the important optical direction is a different axis), you can create a custom plot showing results for light originating from any other direction and of any wavelength.
Note: This plot is available only if you have selected the Birefringence analysis if material data includes optical properties checkbox in the Fill+Pack page of the process settings wizard and the material has measured optical properties.
- Define a local coordinate system so that any one of the three cardinal axes (X, Y, or Z) is pointing towards the direction from which the light is coming.
- Click
() and select 
Custom from the drop down list. - Select Birefringence from the Create Custom Plot pane.
- Enter a name for the plot in the Plot Name text box.
- Select the local coordinate system and the axis which points towards the light source.
- Choose one of the three plot types Phase shift, Retardation or Retardance tensor. For Phase shift, enter a wavelength.
- Click OK.
The plot is displayed and the plot name is listed in the Study Tasks pane under User-Defined Plots.
