Micromagnetic Model

Micromagnetic and numerical background

• 3D dynamic micromagnetic simulation with quasi static field change
• Numerical integration of the Gilbert equation (a=1) for the magnetization and simultaneous solution of Poisson's equation inside and Laplace's equation outside the particles
• Linear interpolation of magnetization and potential on tetrahedrons
• Algebraic system of differential equations solved by a semi-implict backward difference method
