When using the “PM synchronous motor transient analysis”, an unknown variable appears and keeps reporting errors

[CunhaoRong]

At this step, there have been continuous errors and the location of 'ElectricPeriods' cannot be found. I don't understand why this error occurred

@Samuelopez-ansys Sorry to bother you, could you please take a look at this question

[Samuelopez-ansys]

Hi @CunhaoRong What I see from the logger is that you are trying to do plot1.name, but plot1 is a bool, please check the examples 👍
https://examples.aedt.docs.pyansys.com/version/dev/examples/low_frequency/motor/aedt_motor/pm_synchronous.html

If it does not help you, please share a snippet code to reproduce the issue.

[CunhaoRong]

Thank you very much, and I apologize for bothering you again. I downloaded the example you posted and changed the material data part to read local material data, without modifying other parts. In the example file, there is no description of filling in plot1.name. Do I need to manually add the name of this plot? Also, during the simulation process, the variable 'electricalperiod' cannot be obtained normally with the input method used in the example within the desktop interface. If I directly enter 0.005s, it reports an error saying there is no 'electricalperiods' variable, and the chart cannot be established normally. After repeated searches, I couldn't find this variable, so I'm troubling you.If my expression is not accurate or polite enough due to not being a native English speaker, I deeply apologize.

@CunhaoRong could you please debug and check what the create field plot method returns? because I guess it fails. Please check where plot1 is created. The way you are passing the name is correct but if plot1 is a bool it means that the method called to create plot1 has failed thus it returned False so this is the source of your problem and not plot_field_from_fieldplot.

How to solve this?

[gmalinve]

@CunhaoRong did you check what is returned by this method?
plot1 = m2d.post.create_fieldplot_surface( assignment=faces_reg, quantity="Flux_Lines", intrinsics={"Time": m2d.variable_manager.variables["StopTime"].evaluated_value}, plot_name="Flux_Lines", )
if plot1 is False it means that it failed for some reason.
If you are using PyCharm you can try to debug the code and put a breakpoint at this line to check why it fails:

[CunhaoRong]

Thank you very much for your guidance. I will certainly try this and let you know the outcome!
