External B-Field in shape possible?

[p.abt]

Hello,

I am interested in simulating the influence of an external magnetic field on a custom steel shape I have designed.

Is it generally possible to create a homogeneous magnetic field and place my designed box within it? I want to observe how much of the magnetic field is deflected by my box, which acts as a shield for a transformer.

Is a 2D or 3D simulation better here?

Could you recommend useful resources for learning how to perform this simulation in ANSYS Maxwell? I am a complete beginner.

Thank you in advance.

This is the shape I want to analyze

Hi,

I advise to use 3D. The homogeneous magnetic field can be recreated using the boundary condition “Zero Tangential H-Field” (flux normal to the surface) or “Tangential H-Field” (flux tangential to the surface). These boundaries are available in the magnetic solver Magnetostatic and Eddy Current.

If you use the magnetic transient solver, the boundary “Zero Tangential H Field” is available.

Usually, the boundary will be applied in the appropriate surface of the Region (calculation volume).

You can find information about the different boundaries in:

• ·       Maxwell Help > Assigning Boundaries and Excitations for 3D Designs > Magnetostatic Boundaries and Excitations > Magnetostatic Boundaries
• ·       Maxwell Help > Assigning Boundaries and Excitations for 3D Designs > Eddy Current T-Omega Boundaries and Excitations > Eddy Current T-Omega Boundaries

If you want to create the magnetic field without using boundary conditions, please look at the following solution:
