Re: Thermal modelling in Flux - Questions from a beginner
Hello Melih,
About your last request, you will find the example "Brushless IPM motor - thermal analysis" here: https://help.altair.com/flux/Flux/Help/english/UserGuide/English/topics/Examples2D_en.htm
The same example is also available from the Flux Supervisor; it explains the difference between steady state and transient computation. Models and related documents are also available.
Please, update the FluxMotor version if you have the opportunity to do it, version 2023 is available on our website.
Best regards,
Letizia
Re: Thermal modelling in Flux - Questions from a beginner
Hello Melih,
Below you will find answers to your questions.
1. Normally, these losses are computed within FluxMotor so you can take these values from the results you obtained from the working point computation.
2. with the "static thermal model you will have the Steady State application in the model, that means that you will find the steady state temperatures.
3. Yes, there is no automatic export for the transient thermal model.
You could export the "static model" and easily convert the application to transient directly in Flux: [Application --> Convert current application--> to Transient Thermal].
Please remember to add the "volumetric heat capacity" to the materials.
Best regards,
Letizia

Dear sir,
I have done optimization of Lilly pad in three different ways (by changing manufacturing constraints, and optimization settings). please check the results
how to set crontab for vovnotifyd for monitoring
Hi,
If we go 3 months without using vovnotifyd daemon , this daemon goes down and we need to start manually and then kick off a run using the mail notification –
Is there any way we could have a crontab monitoring the nc setup to check for that daemon every so often?

Do you want to learn more about HyperStudy Flux Connections? There is a dedicated eLearning module on learn.altair.com!
The eLearning module, HyperStudy Flux Connection, is now available on learn.altair.com!
In this module, we cover how to connect Flux to HyperStudy and use them together. This module is broken down into a short introduction and a demonstration on how to set up the connection between Flux and HyperStudy. Then some best practices when using this connection are illustrated. Finally, proposed exercises and links to Community posts are presented.

Re: Do the Absolute Error in Performance (Regression) is same as Means Absolute Error (MAE) ?
Yes, this is the same value. As stated in the documentation, the absolute error is calculated by summing the differences between the labels and predictions, and dividing this value by the number of examples.

Re: Seems to be an issue with compatibility of PMSM (FluxMotor) block with LUTs exported from FluxMotor 2023
Hi all,
I'm getting in touch to offer a workaround for this issue. FYI we anticipate it will be resolved in FluxMotor 2024.
It seems the issue is due to a difference in the name of "iron losses" and "torque" headers.
With FluxMotor 2022.3 it was LOSS_IRON
with FluxMotor 2023, it is LOSS_IRON_STATOR.
______________________________________________________________________
With FluxMotor 2022.3 it was TORQUE
with FluxMotor 2023, it is ELEMENT_TORQUE_ELECTROMAG.
_______________________________________________________________________
As a workaround, you can open the .mat file exported from FluxMotor using Compose and the MAT Explorer tool. From there, you can rename the headers accordingly. Once modified, you should save the altered file using the save('path/name.mat') command.

Re: Export particle-particle contact info in EDEM coupling interface API
Hi Qi,
I don't believe that function exists in the coupling interface. You can access particle-particle contact via a API Contact Models.

Re: CUDA custom property across contact and body force
Hi Qi,
If a custom property is going to be used/accessed by multiple APIs, then each one of those APIs has to declare that custom property in both the getNumberOfRequiredProperties and getDetailsForProperty functions. If the custom property name is not the same in both APIs, then you will have two different custom properties instead of one shared property.
