  1. Hi all, let's suppose I want to simulate a two-poles electrical machine with Flux 2D and calculate iron losses on faces. To reduce the domain size I would simulate one-half of the machine setting an even periodic condition (periodicity). Does Flux output losses for only one-half of the machine or for the whole model, automatically taking into account the periodicity? Thank you in advance. Best regards, Marco Biasion
  2. 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. BR, Marco Biasion
  3. Dear sirs, I have some doubts regarding the iron losses model. We are simulating a simple ring core transformer with a material loaded from the library and defined by its k1,k2,k3, alpha1, alpha2, alpha3 parameters. The results from the simulations are quite acceptable. In order to draw a graphic with the power losses versus the maximum induction, I have used the Bertotti modified model equation using the same parameters used by the program. Surprisingly for me, the values obtained with equation are very far from those obtained as a result of the simulation. How can this be possible? What could be the reason for it? Thanks for your help
