Extract iron loss and flux density data for each element of FE mesh

MBIASION

Hi all,

I am working on Synchronous Machines design performing 2D FEM analysis with Flux 2018.

I have obtained the post-processing results concerning magnetic flux density distribution in the domain, iron loss figure computed by means of Bertotti formulation and so on. Now I need to access iron losses and magnetic flux density data for each element of the finite-element mesh. This is needed for further investigations, e.g., compute how many mesh elements have a certain magnitude of magnetic flux density. Is it possible? How can I do it?

I know that 'Computation on points' analysis is available, but it is not useful in this particular case.

Hi,

To export the losses in each node, you can use the function export spatial qauntity and formula starting from different type of suports. To do it :

• Once the project is solved and the iron losses are computed

• Select data exchange >> Export quantity >> export spatial qauntity and formula starting from different type of suports

• A Window opens

• Select face region >> values location : on nodes

• Select export format

• The name of file

• Formula >> select function >> select user : you select the iron losses

 

Best regards

Dear Abdessamed,

thank you in advance for your kind response.

Which file format do you suggest?

I am trying to export B values on nodes first (or at nodes on elements, which is the difference?). To extract B on nodes I have selected 'Formula' --> 'Magnetic volume region' --> B.

 

 

It does not work with any file format:

Dear Abdessamed,

thank you for your help. I have fixed my problems with extracting data.

How did you have solved?

In what format did you exported?

I have exported it in .DEX format. Then I have opened it as a .txt file. That's all.
