Magnetic Permeability #

The magnetic permeability calculation can give you

1. effective permeability of the system
2. magnetic field distribution
3. magnetization distribution
4. magnetic induction distribution

Solved Equation #

$\nabla \cdot B = 0$, where $B = \mu_0 \mu_r H$

• B Magnetic induction
• $\mu$ Permeability, $\mu_0$ the vacuum permeability, $\mu_r$ the relative permeability
• H Magnetic field

Input options #

The following options are needed for the magnetic permeability calculation.

• input->system The choice of calculation system must be magnetic
• input->external->magneticField External applied magnetic field (A/m), if you want to calculate the magnetic field distribution within the composite
  • x Applied magnetic field along x
  • y Applied magnetic field along y
  • z Applied magnetic field along z
• input->solver->ref A property tensor for the reference phase called permeability is needed. Tensor definition is explained [here]
