Data publication: Contactless Inductive Flow Tomography for real-time control of electromagnetic actuators in metal casting
No full textDataset containing the raw and post-processed data used for in the associated publication. Dataset contains the measurements of the flow-induced magnetic field for identification of the compensation parameters and the test data used to validate the model. It also contains the down-sampled velocity profile generated from the numerical simulations, and the reconstructions of the same velocity profile
Data publication: Curvilinear spin-wave dynamics beyond the thin-shell approximation: Magnetic nanotubes as a case study
No full textThis dataset contains the numerical data for our publication "Curvilinear spin-wave dynamics beyond the thin-shell approximation: Magnetic nanotubes as a case study" published in Physical Review B. The data consists of dispersion, magnetization ground states and mode profiles of spin waves in vortex-state magnetic nanotubes of different thicknesses, and has been calculated with the TetraX micromagnetic modeling package. All calculations are described within each subfolder by a jupyter notebook

HZDR Multiphase Addon for OpenFOAM
No full textThe HZDR Multiphase Addon is a software publication released by Helmholtz-Zentrum Dresden-Rossendorf according to the FAIR principles (Findability, Accessibility, Interoperability, and Reuseability). It contains experimental research work for the open-source CFD software OpenFOAM, released by The OpenFOAM Foundation. The developments are dedicated to the numerical simulation of multiphase flows, in particular to the multi-field two-fluid model (Euler-Euler method). Within the OpenFOAM library the multiphaseEulerFoam framework is used for this type of simulation. The addon contains a modified solver named HZDRmultiphaseEulerFoam with the full support of the HZDR baseline model set for polydisperse bubbly flows. In addition a solver dedicated to a hybrid modelling approach (dispersed and resolved interfaces, Meller, Schlegel and Lucas, 2021) named cipsaMultiphaseEulerFoam is provided with the addon. This solver has an interface to the multiphaseEulerFoam framework and utilizes all available interfacial models of it.

TetraX: Finite-Element Micromagnetic-Modeling Package
No full textThis repository holds the first release of TetraX.
Documentation: www.tetrax.software
Helpdesk: discussions.tetrax.software/
Source code: codebase.helmholtz.cloud/micromagnetic-modeling/tetrax
TetraX is a package for finite-element-method (FEM) micromagnetic modeling of magnetization statics and dynamics with the aim to provide user friendly and flexible workflows. Apart from energy minimizers and an LLG solver, it provides 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. Next to support for ferromagnets, TetraX will also provide the first full micromagnetic package for antiferromagnets.
