What TetraX can do for you

TetraX is a package for finite-element-method (FEM) micromagnetic modeling with the aim to provide user friendly and versatile micromagnetic workflows. Apart from energy minimizers and an LLG solver, it aims to provide implementations of several FEM dynamic-matrix approaches to numerically calculate the normal modes and associated frequencies for magnetic specimen of different geometries such as confined samples, infinitely long waveguides, or infinitely extended multilayers. Apart from ferromagnets, the package also supports antiferromagnets as an experimental feature.

The numerical experiments implemented in TetraX are often based on seminal papers. In order to give credit to these works, when conducting a numerical experiment, TetraX saves references important for this experiment to a bibtex file called "references.bib", found in the sample directory. In this file, each entry contains a comment field describing how the reference was important for the computation. When publishing results calculated with TetraX in your research, please also give credit to the works which are important for the numerical experiments you conducted.
