How Can I Solve the Ansoft Maxwell 3D Error for Larger Simulation Regions?

Click For Summary

Discussion Overview

The discussion revolves around troubleshooting errors encountered in Ansoft Maxwell 3D software while simulating magnetic fields and linear induction motors. Participants seek solutions for specific error messages related to current settings and mesh quality.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant reports an error stating that "An external terminal must border the edge of the problem region and coincides with the surface of a 3D object" when setting current on a face, expressing confusion about the software's requirements for larger simulation regions.
  • Another participant asks for clarification on how to set region overlap with the current, indicating a lack of understanding of this concept.
  • A third participant suggests that for an open-ended current path, the simulation region must align with the ends of the current path to ensure proper current flow into and out of the region.
  • A different participant mentions encountering a "Mesh quality of some elements is not accepted by solver" error while simulating a linear induction motor, seeking assistance with this issue.

Areas of Agreement / Disagreement

Participants express similar issues with the software, but there is no consensus on the solutions or the specific requirements for setting up the simulation regions and resolving mesh quality errors.

Contextual Notes

Participants have not fully defined the assumptions or parameters for their simulations, and the discussion lacks detailed explanations of the software's requirements, which may contribute to the confusion.

Hi,
I'm tring to explore magnetic field of the contact system, but when I set the current on a face, i have the next error:

"An external terminal must border the edge of the problem region and coincides with the surface of a 3D object"

I solve this problem when I set region overlap with this current, but then the region is too small.
I tried to make object from face, but it didn't work...
Can enybody help me? I need bigger region...can't understand what requirements have this software for this type of exciatations?

Sorry for my english...

Hi,
I have the same problem, can you describe for me how you solve this problem by setting region overlap with this current? I don't know what it means to set region overlap.

Thank you
 
If your current path is open ended, for example, a copper bar from left to right along Y axis, then your region must be set so that the edges of the region on the left and right will be on the same plane as the ends of the copper bar. This will ensure the current is coming into the region and then going out of the region. If you use percentage to set your region, meaning +y and -y are set to Zero, and x and z can be 100 or 200 percentage.

Hi,
I'm trying to simulate a linear induction motor using ansoft maxwell 3d design, but the following error occurs:

"Mesh quality of some elements is not accepted by solver."

Can anybody help me?
