Help with ANSOFT MAXWELL 3D Magnetic material

Click For Summary
SUMMARY

The discussion focuses on the challenges of assigning permanent magnetic materials, specifically NDFE35, in ANSOFT MAXWELL 3D version 11. Users encounter difficulties in setting the magnetization direction for multiple permanent magnet bodies that are rotated. It is confirmed that Maxwell does not automatically adjust the magnetization direction based on the rotation of the magnet objects, leading to the need for creating separate materials for each rotation angle or using formulas for variable parameters in the material databank.

PREREQUISITES
  • Understanding of ANSOFT MAXWELL 3D software
  • Familiarity with permanent magnetic materials and their properties
  • Knowledge of vector mathematics for setting magnetization directions
  • Experience with material databanks in simulation software
NEXT STEPS
  • Research how to create variable parameter values in ANSOFT MAXWELL material databanks
  • Explore best practices for managing multiple magnetic materials in simulations
  • Learn about the transient solver behavior in ANSOFT MAXWELL 3D
  • Investigate alternative methods for automating magnetization direction adjustments
USEFUL FOR

Engineers and simulation specialists working with electromagnetic simulations, particularly those utilizing ANSOFT MAXWELL 3D for modeling permanent magnets and their behaviors in dynamic environments.

Hi

I'm having an issue ANSOFT MAXWELL :
Assigning a permanent magnetic material to a body (for ex NDFE35) provides me a means of setting the magnetization direction (through x,y,z unit vectors ) inside the material settings

so if i have multiple PM bodies rotated :-
1- do i need to create a specific material for each according to their rotation angle ?
2- how do the transient solver behave if these bodies are moved, will it correct the vectors accordingly?

it seems that I'm missing something, please help
 
Hi Motash,
I ever had the same issue. Then i was try to find it out, and unfortunately Maxwell didn't turn the magnetisation direction with the turning of the Magnet-object. I forgot, if I could use a formula with the angle as a variable parameter value in the XYZ- and coercivity rows at the material-databank, which represents the value of the turning. I'm not sure anymore. (Maybe I was too lazy and I just created several materials). Anyway I didn't like that habit of maxwell 3D v11
