  1. thank you for your help. the problem has been solved. the flux density is now 0.9 in the airgap as per my original assumption.
  2. thank you for your explanation. If I use your formula, the number of turns is actually 32.5 turns in the rotor. So, B=(4*pi() e-7*32.5*300)/11 e-3=1.1T. Can you please explain why you used 2400(8 turns?)? many thanks in advance. I have stuck on this for a while and this is the first time i encountered this problem since upgraded from Flux 11.1
  3. thank you, i will turn my notification on for this thread.
  4. i haven't opened your 3d file in flux but to me the error may have been caused by not setting an infinite box? or have you set the line regions or face regions to things like imposed magnetic induction directions (e.g. tangential?)
  5. forget to add, to run the program, first click mesh domain and then run the test scenario.
  6. First, I would like to thank you for your time and effort for this reply, you have been very helpful and informative. A big thank you. Secondly, you have raised a very interesting point about the material, I was under the impression that 35 is 0.35mm but as you said it represents 100 sheets in total of 35mm. Thank you again and I must say I am very impressed with the support which you guys do for this software.
  7. Hi First I would like to thank you for your time reading this post. I am trying to simulate a 36 pole hydrogenerator to assess its EMF and harmonics. What the attachment contains: 1. geometry, electrical and physics 2. solver steps To run the program, simply mesh the domain and then use the test scenario. The problem im having is that the airgap flux is only 0.3T which is totally wrong. I have deleted all stator winding electrical circuit and simply treating the project as a rotor with windings with no other electrical circuits. I am trying to simply the study and see where the problem is but unfortunately i was unable to get a sensible airgap flux density. would someone please help? regards Marcus 1 ARC T.FLU.zip
