Extract the results from RMxprt #5401

Open lijinlong0308 opened 2 weeks ago

lijinlong0308 commented 2 weeks ago

Dear all, How can I extract the results from an analyzed RMxprt project with python code? the APIs seems not work. Best, Jinlong

Hi @lijinlong0308,

What do you mean the API doesn't work? Could you paste your code snippet? it will help me understand what you are trying to do.

Thanks,

Giulia

Dear Giulia @gmalinve , Thanks for your help. After I run the "rmxprt.analyze()" command, the rmxprt can analyse the performance of the target machine. And we can check the design results by solution data. Now I wanna obtained the information from Design sheet, I try to use the api command "rmxprt.export_profile(setup)", but it end with error. Best, Jinlong

Hi @lijinlong0308,

I'd suggest first to test this example in graphical mode so you can actually see what is going on in AEDT. Then I'd suggest to debug the code to see which properties you can access in an axial flux machine. My IDE of choice is PyCharm and if I debug I can see this: Image Could you please check in graphical mode if you are actually analyzing an axial flux machine and which errors do you get?

Thanks,

Giulia
