Superconductivity (DiVoS)

This code is being developed jointly with the staff from the Departamento de Física de Materiales, Universidad Complutense de Madrid (Spain)

The movement of superconducting vortices on superconducting films grown in substrates with arrays of magnetic nanodefects produces a wide set of experimental behaviours. For example, modifying the value of the applied magnetic field, i.e. the number of vortices, commensurability conditions between the vortex lattice and the array of nanodots are found. This effect can be experimentally measured by minima in the electric resistance ("slow down" in the vortex movement) when increasing the magnetic field [1].

In this work, a computing simulation of these phenomena is described by taking into account different phenomena: the vortex-vortex interaction; the pinning-array interaction; the temperature; etc. Due to the massive amount of computing resources required, Grid, usual HPC and GPU Infrastructures can be used. The creation of an embarrassingly parallel application allows carrying out the experiments in a reasonable amount of time

Molecular Dynamics (LAMMPS)

Sci-Track works on molecular dynamics on different areas of physics of materials. In this regard, the damages produced due to the radiative irradiation of ionized particles into fusion and fission vessels have been simulated by means of different potentials.

Also, research is on-going on transition state theory for solvated reactions beyond recrossing-free dividing surfaces. Thus, it has been demonstrated that it is possible to define such dividing surface in systems with non-Markovian friction.

A new open line of research has been initialized on the simulation of thin crystalline silicon by sputtering deposition of amorphous silicon (around 10-micron thick) with later laser crystallization.

Concentrating Solar Power (Dymola)

Dymola, Dynamic Modeling Laboratory [1], is a complete tool for modeling and simulation of integrated and complex systems for use within automotive, aerospace, robotics, process and other applications. It is able to solve complex multi-disciplinary systems modeling and analysis problems by using Dymola's best-in-class Modelica and simulation technology. Dymola is a complete environment for model creation, testing, simulation and post-processing.

Sci-Track staff has been working on creating a tool for distributing parallel Dymola tasks on a cluster in a efficient and autonomous way, levearing the user for any monitoring action. This work has been carried out jointly with Dassault Systèmes and the Solar Platform at Almería.
