  1. @Alejandro, Really appreciate your kind inputs. I have not gotten chance to work on this problem statement due to chance in work statement. I will however do this evaluation at a later time and will certainly incorporate your valuable suggestions. Thank you very much for the guidance Best Regards Balaji
  2. Dear Experts, I am looking to model induced voltage/current in a simple conductive closed loop which is in the vicinity of a high power carrying conductor. I've not been able to reliably model this scenario in FLUX. Any recommendation would he highly appreciated. Moreover, I believe FLUX is software of choice considering that the frequency is at 60 Hz (Power frequency). Since this is a time varying phenomenon, I believe transient magnetic is the choice for physics. Please advise Thanks and Best Regards Balaji
  3. @Abdessamed , Thank you very much for sharing the python script. I will explore it and learn from it. Thanks a lot for your kind help and support. Best Regards
  4. @Abdessamed, unfortunately, I believe there's some dependency on the 2018 version to collaborate with my colleagues. I've learnt that flux models are not back ward compatible so I am a little apprehensive to update to newer version. I would however explore and work with Altair hw support team to have two versions installed in my computer. Thanks again for the advise Balaji
  5. @Abdessamed , Thank you very much for sharing the model. Really appreciate your time in developing it. Unfortunately, I am unable to open the model. I get the error message which states 'openProject : Execution failed' This may have been due to the flux version. I am using Flux 2018. This is the advanced Error. Would you please re-share the model?

  6. @Abdessamed , I believe these are warnings. If you notice the name at the top of the window in my snapshots it says 'Warning'. Also these came after all time steps of the magnetic transient simulation are completely run. I could view the iso plots, 2D curves for all time steps without any problem. So that means the simulation did not stop in between. Unfortunately, I cannot share my file due to restrictions. However, I could create a dummy project run it and see if I get these warnings. If I get the warnings again, I can share the project with you.
  7. I have been receiving the following warning messages towards the end of my 3D transient magnetic simulations. I don't know what to make out of these messages. Would anyone please kindly advise how to decode these and understand how these effect my simulation results. Have a great day Balaji
  8. Hi @Abdessamed , Would you please advise if there is a tutorial or an example wherein this non meshed coil is used to represent a closed loop. I have been using it as follows. The tube at the center is the coil conductor to which I assigned the non meshed coil. Is this the acceptable and right way using a non meshed coil? If So, Does this represent a loop created by the coil conductor along the non meshed coil? Please advise.
  9. Thank you very much for your kind guidance @Alejandro Rodríguez and @Andoni Garcia. Really appreciate your help. I believe it takes at-least a couple of iterations to get the right size of infinite box for a given geometry. Glad I learnt that. I have now come to appreciate that infinite box size is entirely dependent on the geometry and physics. Thank you very much for your guidance again. Have a wonderful day ahead Balaji
  10. Hi, I have come to learn that, in Flux 3D simulation results vary drastically with change in infinite box size. This, I think may be due to change in mesh. Are there any guidelines in terms of what an ideal mesh setting should be and/or what an ideal infinite box size should be for a typical 3D simulation? In my models, I have been using 'Mesh Domain' option to mesh the geometry. Please advise. Best Regards Balaji
  11. Thank you very much @Abdessamed . Appreciate your help. Best regards Have a great day ahead Balaji
  12. Thank you very much @Abdessamed for your kind response. Appreciate your great help. Best Regards Have a wonderful day ahead Balaji
  13. Yes @Abdessamed , Thanks a lot for your kind response. What about stranded coil conductor? Does it also happen automatically? if So, How do I view or verify or check the connections? Please kindly advise Have a great day Balaji
  14. @Abdessamed Yes, Thanks for answering. Unfortunately, I beg your pardon, That is not my question. My question is about loop area. In the above example, a closed loop is created when cylinder in 3D is connected to a circuit element. What is the area of this closed loop? If the closed loop is rectangular in shape then the area would be length * breadth. Where-in length could be length of the solid conductor which is 100mm. My question is what is the breadth? Please kindly advise your thoughts. Thank you very much in advance Best Regards Balaji
  15. Dear all, My question is pertaining to loop area in Altair FLUX 3D. I have a solid conductor of 100mm length in 3D finite element space. Now, In electrical circuit space I grounded this solid conductor with a ground element. What is the loop area of this setup? please advise. (Kindly refer image for more illustration) Best regards Balaji
