  1. Thanks for your reply Abdessamed. The thing is that, if you create an only conductor region, you'll need to insulate every turn not to create any short-cut as I describe in the image:
  2. And why does this happen? I've applied the same mesh to the same geometry with 10 times smaller depth, so I don't think that it's due to the overmeshing...
  3. I'm trying some meshing techniques for some simulations, and I would like to know how it is the best way to mesh a face / Volume / Region / ... I suppose that depending the meshing quantity, I'll get different results. And also, the best meshing way for the user depends on applying the less meshing point quantity, for the most precise result. Saying in other words, if I add more points in the meshing tool, the result will not change. Correct me if I'm wrong please, but is it true that the check mesh checks the precision of the mesh in all the system? Including Aided & Relaxation mesh areas. And how would be the way to check the mesh of an specific face, volume, region, line... without drawing upon the solver?
  4. Hi to everyone! I'm modelling a copper coil to check skin and proximity effect (first without the core). When I was extruding the faces I found that it´s necesary to assign face regions in every conductor surfaces not to provocate short-cuts. Or on the other way, would be enough to define the material as "Solid Conductor Region Described By Impedance"? Anyone knows another way to do the same easier?
  5. Thank you so much! The 2 circular figures (left and center) were only to check the differences between the standard and the mapped mesh. Any experience in this respect?
  6. Hi there! I'm calculating the resistance and the skin effect of different shapes of copper conductors at varying current & frecuencies. I started solving only with a frecuency multi-value scenario due to the fact that the solver trigger an error. I would appreciate some help. Thanks for all, Andoni Resistencia_Skin_Effect.zip
  7. Where can I acquire that tutorial? Thanks,
  8. Hi Alejandro! Thank you for your answers. The formula was the Steady Bertotti modified with he mass representation in there; ignore it, I was complicating matters. The trouble dwelled in a small mistake I made in the geometry, that was the reason why I got a "strange" solution.
  9. 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
  10. Hi everybody. I'm simulating a FeSi transformer core for calculating iron losses. In this regard, I'm using the Bertotti modified coeficients whose parameters are obtained from the Bertotti Modified (Flux's folder) excel worksheet . Alright up here. The problem arises when I have to use the solver on the worksheet: I would like to know what are the input parameters (k1 k2 k3 a1 a2 a3), because the result will be different according to those numbers. Thanks lot.
  11. First of all, thanks for your answer Alejandro. I'd seen those documents and I actually know how to structurate a core with windings. But the reason that I openned this topic, sorry if I didn't have explain correctly, is because I would like to know the algorithm that this program utilize when simulating. I understand that it focuses on every points of the meshing but I want to dig deeply specially in core losses. Take it into account that I introduce the 6 Bertotti modified parameters (that I get from the spreadseet of Flux's file folders) into the material information for calculating the losses. I also know that there's another way to calculate the Berttotti (NON MODIFIED) losses, is this way more accurated? Thanks for all.
  12. I'm doing the final degree project using FLUX (I'm new here) and I would be so grateful for some help. What I have to do is firstly simulate the electromagnetic behaviour and losses of a specific transformer core at some frecuencies (50 Hz, 1kHz), just for make a comparison of these results with the reality behaviour. If a deviation exists (I see it possible) I would like to search out where it comes from. This is so important due to fact that after this step, I would have to simulate it at higher frecuencies (150kHZ or more) and those simulations would provide a more reliable results. To summarize, I would like to know how the simulation solver works, wich formula applies to get the results regarding power losses; or where can I get that information. So appreciated, sincerely Andoni
