Abstract

This project brings together researchers in electromagnetic and stochastic computational techniques. Many researchers of the team are involved in the solution of electromagnetic compatibility problems, where incoherent radiators, semi coherent emitters and complex devices are quantified. Usually, the involved geometry is large and may have highly complexity in field pattern. Moreover, chaotic structures are investigated and the results can be obtained only as an ensemble average of simulations by changing geometrical parts or sources. Three dimension simulations of complex sources in complex environments require Tier-0 machines. All the participants of this team have a background in the parallel computation. The group of Ancona developed an FDTD code for the simulation of reverberation chambers; the group of Granada developed “UGRFDTD”, a general purpose (EMC-oriented) state-of-the-art FDTD solver; the group of York developed “Vulture”, an open source FDTD solver for electromagnetic simulations, and the group of Nottingham developed GGITLM a TLM based time domain simulation code. We participated to previous PRACE projects and domestic calls. We will use the same computer code of the previous projects "CSSRC - Complete statistical simulation of reverberation chamber", approved during the PRACE 7th Regular Call for the year 2013- 2014, "ASOLRC - Advanced simulation of loaded reverberation chambers" approved during the PRACE 9th Regular Call for the year 2014-2015 and "SREDIT - Simulations of Radiated Emissions in Densely Integrated Technologies" approved during the PRACE 13th Regular Call for the year 2016-2017. Our codes are capable to simulate different geometries as set of stirrer angles in the reverberation chamber and complex sources for the propagation of the stochastic noise emissions. The code of Ancona was optimized for the FERMI and Marconi-KNL architectures during all the previous PRACE projects and the code of Granada was optimized for Marconi-KNL architecture during the PRACE 13th Regular project. The Ancona code is mainly divided in three modules: 1) an electromagnetic time domain solver; 2) a fast Fourier transform; 3) a statistical module to obtain the cumulative results. All the modules were previous optimized for high-performance parallel computers using hybrid method (MPI and OpenMP) and they was used successfully in the previous PRACE projects. The availability of a code, that solves the previous three steps in a unique job, makes the simulations very appealing. Moreover, the availability of an optimized simulation code will give the results in short time avoiding long measurement campaigns. The team is a part of the group of the COST Action IC1407, that began in April 2015. In particular, the works of WG1: numerical methods for addressing the propagation of stochastic fields and WG3: equivalent models of noise sources. COST project provides financial support to travel and PRACE project provides computer access, so the two projects are complementary. Not all the participants are mainly working in the EMC topics, they are mathematicians and physicists working on the more general topic of chaotic systems making this project multidisciplinary.
