  1. Hi, Youi will find attached a pdf file explain how to mesh the air gap to get a periodic cogging torque. This document is available in Altair connect. To get it: Connect to Altair connect Select : documentation In search put: flux cogging torque Best regards. Cogging_Torque_Computation_and_Meshing_for_Radial_electrical_motors_in_FluxNews67feb2015.pdf
  2. Hi, Can you send me a screenshot of the error message. Best regards.
  3. Hi, Can you try to import the device as a step file. Best regards.
  4. Hi, To reduce the number of nodes on your project you can edit the mesh and change the option. To do it: When you open your Flux project >> in the top select mesh Select aided mesh >> edit You can change the mesh data The second option deactivate the aided mesh and create your own mesh (for example mesh point discretization, line discretization). Best regards.
  5. Hi, To create your LIM in Flux 3D, I suggest you use the same method as the 3D flux supervisor example (Flux Supervisor >> open example >> select application note >> linear motor) available in the supervisor on a permanent magnet linear machine. Best regards.
  6. You delete the mesh and use zip format. best regards.
  7. Hi, Transversal relative permeability is the material permeability in the direction perpendicular to Br. Usualy the value is close to 1. Best regards.
  8. Hi, The FluxSkew export is available juste for the induction motor. Best regards.
  9. Hi, If you want to take into account of the skin depth you need: Define the skin depth thickness Define a mesh generator type layer. To do it: Mesh >> Select mesh generator >> new >> mesh generator type: select layers >> give all the information of the height layer Once the mesh generator is defined >> select the volume on which you need to take into account of the skin depth and assign the mesh generator Best regards.
  10. Hi, I just checkd using FluxMotor 2019.1, I reached to export a FluxMotor to the FluxSkew. When you select export >> Flux Skew >> on the right you need to enter: The name of the model The path where the model will be saved Selct if you need the full goemetry or no Best regards.
  11. Hi, Unfortunately we don’t have any example about coil using Litz wire. But if you want to take into account of the proximity effect you can use coil conductor region with loss. This region is available only in steady state AC magnetic. Best regards
  12. Hi, To limite the number of nodes you need to create your own mesh. For exampel you can create a point discritisation or line disctrtiztion and assign it to the points and lines. Depending on the mesh information you can have a number of nodes. Other thing if you use the automatic mesh, you can change the infomation of the mesh. To do it : Mesh >> aided mesh >> edit Change the mesh information Best regards.
  13. Hi, When you extrude the faces you will create a volumes, you don’t need to assign any face region just you need to create a volumes region and assign it to the volumes. If you use the same material for all the volumes you need just to create one volume region and assign it to the volumes. To do it : • Click on the physic (in the top, not in the data tree) • Select volume region • Select assign region to volumes But if you have several region you need to create several volume regions and assign it for each volumes. To see the losses and the proximity effect, you need to use a solid conductor region for each volume. Don’t forget to assign the internal and external terminal for each solid conductors. To o dit : • Click on the physic (in the top, not in the data tree) • Select assign terminals to solid conductors Best regards.
  14. Hi, Unfortunately it is not possible to export no meshed coil because there is no volumes. But If you want to export your winding, in this case you need to represent it with mesh coil. Best regards.
  15. Hi, To export the losses in each node, you can use the function export spatial qauntity and formula starting from different type of suports. To do it : Once the project is solved and the iron losses are computed Select data exchange >> Export quantity >> export spatial qauntity and formula starting from different type of suports A Window opens Select face region >> values location : on nodes Select export format The name of file Formula >> select function >> select user : you select the iron losses Best regards
  16. Hi, To export the losses in each node, you can use the function export spatial qauntity and formula starting from different type of suports.

  17. Hi, If you use just the Flux context, you have just one choice to export your device (DXF file). But If you want to export your device in different format (step, sat…) you need to entrer in the modeler context. Once you are in the modeler context >> project >> select the format that you want. Best regards.
  18. Hi, Can you check the different conditions that you use in your project (boundary condition) The second point, the unite that you use to compute the magnetic field analytically ? Can you share your Flux project ? Best regards. Best regards.
  19. Hi, You are right, following the steps in the pdf file, when I load the macro I get the same error message as you. To avoid this error messgae, once the goemetry is created you need to unload the Overlay. To do it : • Leave the context Overlay once the goemetry is created • Go in the extensions >> select Use overlay >> right click >> select unload Once the overlay is unload, you load the macro and run it. With this modification it work well. Best regards.
  20. Hi, As you can see in the PPT file, it is not possible to use a face mapped mesh on your configuration. but there is another way to do it, you create a line decritisation (for example arithmetic and assign this decritisation to the lines of the faces (6 and 7). Best regards.
