 nd practical knowledge\n\nAgenda: \n\nDay 1 \n\n9.00 - 10.00:\nIntroducti
 on to Computational Mechanics:Mariano Vázquez\nWhat is behind a simulatio
 n code? Main concepts. The Physical system and its Mathematical descriptio
 n\nDiscretization: divide and conquer Discretization: algorithms and codes
 \n\n \n\n10.00 - 11.00:\nThe CompBioMed project: an example of engineerin
 g simulations in the biomedical industryMariano Vázquez\nThe European Cen
 ter of Excellence in Computational Biomedicine is a joint effort to link e
 ngineers to medical research through the use of large-scale computational 
 resources and efficient parallel programming. Biomedical research presents
  perhaps the most extreme and challenging simulation scenario for computat
 ional mechanics codes. In this talk we will describe how this project targ
 ets medical devices industry\, pharma and clinical research.\n\n \n\n11.0
 0 - 13.00:\n\nHPC and fluid-structure interactionJuan Carlos Cajas - Beatr
 iz Eguzkitza\nWe present a general coupling strategy for multi-physics pro
 blems. The basic idea is to have independent codes\, one for each physical
  problem\, and communicate the coupling variables using MPI. Special inter
 est on Fluid Structure Interaction (FSI) problems. Usually\, the multi-phy
 sics problems involve different space and time scales\, which can lead to 
 situations in which optimized algorithms for the individual problems are u
 seless in the coupled one. Thus\, different coupling algorithms and relaxa
 tion schemes are considered and tested. Cases for FSI problems in wind gen
 eration and bio-mechanics are considered.\n\n \n\n\n14.00 - 16.00:\nParal
 lel algorithms for Computational Mechanics:Guillaume Houzeaux - Ricard Bor
 rell\nWhat is parallelization in a simulation code? Paradigms and scenario
 s.\nDescription of parallelization schemes. Parallel algebraic solvers and
  solving strategies.\n16.00 - 18.00:\nComputational Fluid Dynamics (CFD): 
 turbulence\, driving and sailing:Herbert Owen - Oriol Lehmkuhl\nCFD is one
  of the fields of Computational Mechanics where HPC and parallelization is
  more influential\, due to the Physical complexity of the systems. This ta
 lk describes incompressible flow applications in automotive industry and y
 acht design. The Physical description includes turbulence modelling\, free
  surface and floating rigid bodies.Day 2:\n-----\n9.00 - 11.00:\nIntroduct
 ion to Computational Solid MechanicsEva Casoni - Gerard Guillamet\nThis ta
 lk provides knowledge in all the technical aspects of Solid Mechanics anal
 yses\, which are in high demand in many industries.\nSolid mechanicians fo
 cus on the deformation and failure of materials with a defined rest shape 
 for real-world applications. A solid mechanician envision the final applic
 ation and uses theoretical\, experimental\, numerical and computational to
 ols to solve the problem.\nA general view of the most used and useful appr
 oaches and constitutive theories applicable to the deformation and fractur
 e of metals\, composite and biological materials will be done in this talk
 \, covering the general aspects of the modelling and solution approach.\n1
 1.00 - 13.00:\nIntroduction to mesh generation for simulationXevi Roca - A
 bel Gargallo\nThis course is a brief introduction to fundamental mesh gene
 ration approaches used in academic and commercial simulation. Mesh generat
 ion methods have succeeded in decomposing highly complicated domains by fi
 lling them with distributions of different types of elements such as trian
 gles\, quadrilaterals\, hexahedra\, tetrahedra\, pyramids\, and prisms. Th
 ese meshing methods are used in a daily basis by computational engineers a
 nd scientists to obtain numerical predictions over complex geometrical con
 figurations. The course introduces different types of: geometrical represe
 ntations\, meshing methods\, element types\, boundary approximations\, qua
 lity measures\, sizing approaches\, and software packages. This is an intr
 oductory course intended to facilitate the election of the proper mesh gen
 eration methods for simulation.\n14.00 - 16.00:\nN-bodies Contact Detectio
 n and ResolutionCristóbal Samaniego\nThe talk is divided in two main subj
 ects:\nFirst\, the contact detection algorithm prevents interpenetration b
 etween bodies by estimating the time of collision. The algorithm includes 
 efficient search methods to drastically reduce the number of operations wh
 en we estimate the time of collision between a pair of bodies.\nSecond\, t
 he contact resolution algorithm changes the velocity of the bodies in cont
 act in order to prevent interpenetrations. This subject also includes meth
 ods to reduce the execution time. Also\, other aspects of the n-bodies con
 tact are described to improve and to have a more robust method to solve th
 e interaction between rigid solids.\n16.00 - 18.00:\nIntroduction to numer
 ical combustionDaniel Mira\nThe energy market is leading towards cleaner s
 olutions in order to reduce pollutant emissions from combustion systems.\n
 Nowadays\, numerical simulations have become an important tool to provide 
 insight into the dynamics of flames as well as the overall performance of 
 the entire combustion device. In particular\, turbulent combustion is a co
 mplex phenomenon involving the interaction of chemical reactions and heat 
 release with turbulent flow structures. This interaction leads to the deve
 lopment of a wide range of time and length scales\, coupled to hundreds of
  species and reactions\, so the requirements in HPC are an essential aspec
 t to address this problem.\nThis session addresses some fundamental aspect
 s of combustion modelling with emphasis on HPC and practical examples of g
 as turbines.Day 3:\n-----\n9.00 - 11.00:\nScientific visualizationLuz Calv
 o\nThe visual representation of scientific data has been a key component o
 f science\, advancing thanks to it or directly causing advances. Nowadays\
 , the field of scientific visualization is growing fast\, thanks to the te
 chnological explosion and a renewed interest of society in design and aest
 hetics. In this course we will survey the field of data visual representat
 ion\, discuss about available tools\, and touch on narrative topics that r
 esearchers can learn on their own to improve their graphical communication
  skills. We will explore elements of computer graphics\, human-computer in
 teraction\, perceptual psychology and design in addition to data integrity
  to learn how to present this data to an observer in a way that yields ins
 ight and understanding.\n11.00 - 13.00:\nBiomechanics: Cardiac Computation
 al ModellingJazmin Aguado-Sierra - Ruth Arís\nFrom an engineering point o
 f view\, Biological systems are amongst the most complex Physical systems 
 in Nature. Multiscale\, multiphysics\, great variability\, large uncertain
 ties\, numerical issues\, validation difficulties and extremely complex ma
 thematical models are amongst the common features of computational biomech
 anics. Considering that all these problems usually show up altogether\, th
 e use of HPC-based simulations in biomechanics is a must.\nIn the BSC's CA
 SE department\, we focus in simulations at organ level. The "Alya Red Card
 iac Computational Model" is a paradigmatic example\, which will be deeply 
 described in the talk.\n14.00 - 15.00:\nHPC Challenges in the Oil Industry
 Mauricio Hanzich - Josep de la Puente\nAn introduction to the numerical me
 thods involved in the modelling\, migration and inversion of seismic and E
 M data for hydrocarbon exploration. Talk will include: why the geophysical
  exploration matters\, what are the main challenges today and the future t
 rends and how HPC is mandatory for many geophysical problems.\nFrom method
 s and algorithms for geophysical exploration to HPC software on modern arc
 hitectures. Talk will include: main issues to be tackled for HPC applicati
 ons for Oil Industry\, current programming models and paradigms for such a
 pplications and current state of HPC environments and future trends.\n15.0
 0 - 16.00:\nSupercomputing for fusion energy applicationsXavier Saez\nFutu
 re energy requirements set an unprecedented challenge for our\nsociety. Fu
 sion energy is uniquely placed to meet the growing energy\ndemand. In this
  talk illustrative examples of computer modeling in the\nfusion energy fie
 ld are discussed\, with special emphasis in applications\nrequiring superc
 omputing resources.\n16.00 - 17.00: meteo / atmospheric (arnau / matias)\n
 Atmospheric transport modelling &amp\; High-resolution meteorological mode
 lling using CFDMatías Ávila - Arnau Folch\nExample case 1: volcanic ash 
 dispersal and civil aviation - Atmospheric transport models are used to si
 mulate the dispersal of any substance in the atmosphere. Applications incl
 ude dispersal of pollutants or air quality modelling\, among several other
 s. In paricular we focuss on volcanic ash dispersal and its impacts on civ
 il aviation.\nExample case: assessment of wind energy resources - CFD is t
 he pivotal tool to increase the spatial resolution of mesoscale Numerical 
 Weather Prediction Models. This talk describes how turbulent CFD models ar
 e used to assess winds and turbulence in the microscale\, focussing on the
  evaluation of the wind resource for eolic energy.17.00 - 18.00:\nAtomisti
 c simulations in material science\n\nGeorge Huhs - Stephan Mohr\n\nBe it t
 he design of lighter and more stable materials for a car\, the development
  of longer lasting batteries for a smartphone\, or improving the efficienc
 y of solar cells -- the quest for novel materials is a key aspect in many 
 technological branches. Material science is thus a very broad field\, unit
 ing numerous theoretical and experimental approaches. In this talk we will
  present methods based on a quantum mechanical description on the atomisti
 c level. This approach gives insights into many characteristics of materia
 ls that might not even exist yet. To this extent complex equations must be
  solved\, requiring large supercomputers for treating realistic problems. 
 Recent developments push the frontiers of material science even further by
  applying big data analytics to collections of calculations. Finally we wi
 ll present some examples and applications\, demonstrating how these method
 ologies are valuable components in the toolchain for designing novel mater
 ials.\n\nEnd of Course\n\nhttps://events.prace-ri.eu/event/528/
