Pre-Analysis & Start-Up

Governing Equation

Magnetostatics is the study of magnetic fields in devices where the magnetic field is generated from DC (steady) currents and/or permanent magnets.  Magnetostatics is a special case of Maxwell’s equations, which form the basis of electromagnetism.  

For magnetostatics the electric field inside of a current carrying coil is completely decoupled from the magnetic field, and the following Maxwell’s equations are solved for magnetostatics -

Where ∇ Where∇denotes divergence, H is the magnetic field intensity, J is the current density, and B is the magnetic flux density.

Now that the the pre-calculations are finished, we are ready to begin the simulation in ANSYS AIM. Open ANSYS AIM by going to Start > All Apps > ANSYS 18.2 > ANSYS AIM 18.2. Once starting page has opened, select the Magnetics template as shown below.
