What does the ELTORQ_ROTOR_R parameter value 0.01067707551731 represent in electric motor simulatio

Hello Harmony,

Thanks for writing to us.

1..The value of parameter you use in the output window corresponds to value of EmagTorque at last step of simulation. You can also look at the Values, under the plot to see the same last step value.

2. This only represent the last step of simulation.

3. This is electroMag torque value corresponds to last step- Not Average torque or RMS torque for total simulation time.

4. ElectroMagTorque is caluclated by Virtual works method in Flux.
Explanation of results: energy, force, torque

Let me know if you have questions.

Best Regards,
Charishma.

Hello Thanks for your reply

But i am trying to export the result from Flux 3D to HyperStudy and the one the output parameter i need is the electromagnetic torque so as to maximize its value in HyperStudy.

How can i get either the maximum or RMS values exported or can i use this value of

(0.01067707551731) for the optimization in hyperstdy? will it provide the desired result ?

Thanks as i await your response

Hello,

You can refer the example in Flux Supervisor. Flux 2D>Co- Simulation> Flux-HyperStudy. The procedure remains same in case of 3D also. You need to define the parameters you want to export. In this case you can create a parameter I/0 using parameter defined by a formula -Max(ELTORQ_ROTOR). Now, when you use generate component for HyperStudy in Solving menu, you will find this in component output, available parameters in Physical. Hope this is useful.

If you still find it difficult understanding how to do this. I request you to create the support ticket, we are happy to help you.

Thank you.

Hello Thanks for your reply

But i tried creating the IO parameter like you suggested but i keep getting syntax error. can you please work me step by step on how to achieve this? my aim is to be able to export either the max,rms, or mean value of the electromagnetic torque to hyperstudy for optimization.
Please can i have a step by step guild on how to go about this ? i will really appreciate
Thank you

Hello,

My intention was to let you know, the workflow. Apologies, for confusion. If you want to write Max (Torque_Rotor), syntax would be Max(TorqueElecMag(ROTOR),0) in Flux.

I have better workflow instead of creating parameters on our own. You can use Macro> Analyze 2D curve this automatically creates all parameters for you. Here is a document on how to use the macro. Please refer the document, while selecting 2D curve choose torque curve.

Also, a link for forum question on the topic:

Hope this is helpful.

Thank you,

Hello
I used the postprocessing python step you suggested but here are the problem and questions i have. i will attach pictures to each problem and the error i got.

1. how will i create the post processing python file? Because what i did was write an external code (in VScode) and save it in .py format in the same path as my project. is this the right way ? (picture attached)

I think i am not implementing the post processing python file properly. also i have already loaded the macro but i dont know what i am doing wrong. what i did was to drag and drop the optimal_torque_test.F2HST to the model and then click import variables and then Next and ran definition which brought out the error below.

so please can you help me with the proper step how to go about this ?

Hello Harmony,

Macro I suggested Is to create min, max and mean parameters of torque in Flux, so these can be exported to Hyperstudy. I have attached document on how to load macro and obtain parameters.

I have few questions for you before answering the questions in such case, I recommend creating a support ticket for Flux group or email hwsupport@altair.com,( so our team will raise a support ticket) .We can help you clearly and clarify all your questions in support ticket. Please share you error messages in the support ticket. so our team can take a look at them and answer your questions. I don't recommend sharing models or file or screenshots publicly here.

Thank you,
Charishma.

Hello thanks for your help

I have sent a mail to  hwsupport@altair.com. But i will really appreaciate if my question can be answered here too because i am running on a deadline and starting another ticket means i have to start explaining everything again from the start.

I would be grateful if my question can be answered here too on the community. Thank you so much for your help

Hello Harmony,

If possible I will take the support ticket myself, or I will make sure, I will give background and objective of the project in ticket. When the ticket is created, make sure you share the model in the ticket . This way we can quickly help you generate Hyper study project .

Also, Postprocessing .py file is optional. we can still make hyperstudy connection without them. Refer to article below.

Thanks,
Charishma
