1. EUA4X 2005 Annual Conference

Organizers: Giorgio Fotia (CRS4/TCN Consortium) and Cristina Marras (TCN Consortium). The videos present the five plenary sessions of the conference illustrating the latest developments on computational technologies for industry and their application to many other computation-oriented areas. The lecturers cope with the current and future scenarios in computational techniques such as mechanics, multidisciplinary optimisation, computational material science, and computational medicine & biotechnology.

2. High Order Discretization Methods for Computational Physics

Organizers: Herman Deconinck and Mario Ricchiuto (VKI). The course focuses on very high-order numerical schemes for simulating fluid flow and convection dominated physics in general, in particular those methods allowing the use of unstructured grids. The course offers a wide overview and recent developments of different methods with the ultimate objective to create a bridge between applied mathematics (numerical analysis) and fluid dynamics (real application). Introductory courses present Finite Volume and Finite Element Methods in a unified framework, and discuss discretizations that exploit the structure of the governing equations. Then a large number of (unstructure grid) frameworks for constructing schemes of very high-order of accuracy are introduced, and their state of the art discussed: this includes: Discontinuous Galerkin and ADER Discontinuous Galerkin schemes, Spectral Element and Spectral Volume methods, Compact Finite Difference schemes, Residual Based Compact and Residual Distribution schemes and finally well-balanced WENO discretizations.

3. Advanced Finite Element Methods for Continuum Mechanics

Organizers: Giorgio Fotia (CRS4/TCN Consortium) and Anna Pandolfi (Politecnico di Milano). This course focuses on the finite element method applied to non-linear problems, illustrates classical and innovative solution procedures, and points out the issues related to the implementation of numerical algorithms. In particular, various topics of discretization techniques for non-linear analysis are introduced, including: finite kinematics, solution approaches (Total Lagrangian, Update Lagrangian), constitutive models (linear and nonlinear elasticity, rate-independent plasticity, viscoelasticity and viscoplasticity), variational formulations for non linear problems, fracture and adaptive meshing techniques, and frictionless and frictional contact problems.

4. State of the Art in Numerical Grid Generation: from Theory to Practice

Organizers: Rosa Maria Spitaleri and Francesca Pistella (CNR-IAC). The course provides a state of the art in numerical grid generation and deals with effective solutions of domain discretization problems occuring in computational field simulations. Participants are introduced to appropriate solution methods, to structured and unstructured grids or mixed approaches.

5. High Order Methods for Large Scale Industrial Applications

Organizers: Fabio Maggio (CRS4) and Giorgio Fotia (CRS4/TCN Consortium). The workshop presents some of the works of experts of innovative mathematical methodologies facing advanced end-users from industry and engineering. The focus is on effective results, real needs and expectations for the middle- and long-term research and development activities. The attempt is to merge different knowledge and to set-up competitive research aiming to cross-disciplinary analysis of complex, large scale applications in these fields.

6. Computational Aspects of Structural Acoustics and Vibration

Organizers: Roger Ohayon (CNAM) and Goran Sandberg (LTH). The aim of these lectures is to address recent advances in the computational modelling of structural acoustics and vibration. The E-atelier publishes online the 6 lectures of R. Ohayon (CNAM, Paris, France) on Interior structural acoustics linearized equations for an elastic structure containing an inviscid fluid, Choice of state variables, Corresponding variational formulations, Discussion on the symmetry of the formulations, Finite element discretization and reduced order models for modal analysis case; and the 7 lectures of G. Sandberg (LTH, Lund University, Sweden) on Basic finite element formulations for fluid-structure interaction, the use of different variables, the modal reduction of FSI, the illustration of software implementation, and practise of examples to demonstrate the possibilities of FSI.

7. Computational Techniques in Food Engineering

Organizers: Michele Chiumenti (CIMNE) and Stefano Odorizzi (TCN Consortium). The curse on Computational Techniques in Food Engineering covers a wide scope of research on the use of mathematical and computing techniques in food processing. Its main objective is to present the state-of-the-art in computational methods for the optimisation and control of food technologies from a scientific base. The course deals with simulation and modelling of unit operations and process plants, food process optimisation, decision support systems, and food quality control.
