Stiffness in Micromagnetic Simulations
In this paper we investigate stiffness in micromagnetic simulations in the ODE context. We introduce some pragmatic measures of stiffness based on the total number of time steps taken by a non stiff and a stiff method to solve the LLG equation, and the cost of each method per time step. We present a family of micromagnetic calculations that simulates materials with strong exchange coupling betw...
متن کاملMicromagnetic simulations of magnetic domain wall dynamics
This summer project reproduces the foam experiment from previous summer but with oilwater emulsions. Increasing the viscosity of oil changes the droplets from soft to hard as well as the behavior from Newtonian liquid to granular matter. The expected outcome is Bachelor’s or Master’s Thesis or similar report depending on applicant’s background. The applicant is expected to have keen interest in...
متن کاملAccelerate micromagnetic simulations with GPU programming in MATLAB
A finite-difference Micromagnetic simulation code in MATLAB is presented with Graphics Processing Unit (GPU) acceleration. The high performance of Graphics Processing Unit (GPU) is demonstrated compared to a typical Central Processing Unit (CPU) based code. The speed-up of GPU to CPU is shown to be greater than 30 for problems with larger sizes on a mid-end GPU in single precision. The code is ...
متن کاملFastmag: Fast Micromagnetic Solver for Large-scale Simulations
Micromagnetic solvers have a high predictive power and are important for our ability to analyze and design magnetic components. Simulating a complex structure may be very time-consuming and the development of fast computational methods for micromagnetics is of high importance. Modern and future computational tools should rely on parallelization to allow for continuing scaling of the computation...
