    LICENSE ERROR

    Thank you so much for your hints. I have just checked this .dat file and my license expired two months ago, that is, 1 year has already passed. I am gonna re-register again. Stay safe. Marco

    LICENSE ERROR

    Dear all, I got my student license to install Flux 2D on my laptop almost a year ago. I removed such a software from my computer a couple of months ago, now I need it again. The installation process was fine, but while opening one of my old projects (created a year ago with the same software) the following notification displays. Can you please help me to fix this? Best regards, MB
  3. Unfortunately I cannot update the software.
  4. Hi, thank you for your kind response. I have just tried to run your project but this error occurs. I have Flux 2D 2018.1 on my PC. It seems weird to me... It is a 2D project... Any ideas? BR
  5. Hi Abdessamed, any news? Best regards, MB
  6. Here it is. Please try to simulate it setting the following values for I_PEAK parameter (Parameter I/O): 1) 0.08 - converges; 2) 1 - does not converge; 3) 10 - converges; Hope to hear from you soon. Thank you in advance, MB
  7. Hi Abdessamed, thank you for your kind response. Of course it is a numerical problem. However, following your advice I cannot accurately simulate my device. I must simulate it using its magnetization curves: as a consequence, relative permeability is a nonlinear function of magnetic field strength. Moreover the difference in terms of permeability along rolling and transverse direction is not that relevant: less than an order of magnitude. Best regards, MB
  8. Hi all, I am simulating kind of single-phase transformer with Grain Oriented materials. I am modeling the iron core with a 'magnetic non conducting region'. Magnetization curves along rolling and transverse direction are characterized up to saturation and their measurements data are smooth enough. They are modeled through an 'anisotropic spline saturation' tool removing the knee in the Rayleigh zone, as suggested in the User Guide. Performing a transient analysis, the solver is not able to converge during Newton-Raphson computations for medium-high field strength values. On the other hand, when simulating very low and extremely high field strengths, the solver converges with no particular issues. Can you please help me to figure it out? Thank you in advance, MB
  9. Thank you Alejandro! Electromagnetic torque vs time output refers to the whole machine instead, right?
  10. 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
  11. I have exported it in .DEX format. Then I have opened it as a .txt file. That's all.
  12. Dear Abdessamed, thank you for your help. I have fixed my problems with extracting data. BR, Marco Biasion
  13. 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: BR, Marco Biasion

  15. 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
