WINGSAIL TECHNOLOGY DEVELOPMENT

Biscarri Consultoria col·labora en el projecte BOUND4BLUE que desenvolupa un sistema de propulsió de vaixells amb veles rígides de perfil aeronàutic. L’objectiu principal d’aquest sistema és la aplicació a la producció d’hidrògen a partir de l’aigua del mar, mitjançant hidròlisi, amb l’electricitat produïda per les turbines adosades al propi casc del vaixell cisterna, transformant així l’energia del vent en electricitat que finalment s’emmagatzema en forma de hidrogen, i amb oxigen com a “residu”.

La missió de Biscarri Consultoria és la posada a punt de models de simulació CFD amb el programari open source OpenFOAM.


Els model numèric està parametritzat, adaptant-se de forma automàtica a les variacions geomètriques que s’hi introdueixen. D’aquesta manera, en poder simular i comparar diferents configuracions molt àgilment, s’afavoreix enormement l’optimització del disseny de les veles i el seu layout en el vaixell, per tal de maximitzar les prestacions del sistema per a una diversitat de condicions de vent.perfils_pressioOpanFOAM és una eina CFD gratuïta de codi obert molt potent i versàtil, optimitzada per a executar-se en entorns HPC (supercomputació paral·lela).

Cast Copper Furnace: Thermo-Mechanical analysis using Code_Aster

A brief summary of a Biscarri Consultoria project developed for La Farga Group, consisting on the thermo-mechanical simulation of a Cast Copper Furnace. The CAE software employed is the open-source suite Code_Aster. The numerical model consists of the structure finite element mesh (shell elements) and the inner refractory brickwork finite element mesh (solid elements), coupled through contact algorithms.

A first linear thermal analysis calculates the temperature distribution of the whole model (refractory + structure) arising from the service temperature inside the furnace.

A second non-linear static analysis calculates stress and strain distribution on the model due to gravitational loads plus thermal dilatation loading, which is applyed in an incremental way through 100 load steps. This analysis is fully non-linear because of the presence of contacts, the use of elasto-plastic material law for the steel and material properties being temperature dependant, such as Young’s modulus and Thermal Dilatation Coeficients.

The figures show stress distribution in the structure and the refractory brickwork, and deformed geometry by gravitational loads.

Alya Red: a computational heart

An extraordinary application of BSC’s multiphysics platform Alya which is starting a new path in medical research. High Performance Computing (HPC) has reached a point where very complex systems, such as a human heart, can be simulated.

What simulation essentialy provides is the capability of understanding and learning the physics underlying things, giving a new and deep perspective on the way nature works. From the evolution of the universe, to the puzzle of biological systems.

CFD Experiment – Team 30

The “CFD Experiment” or “HPC Experiment” is an HPC-as-a-Service experiment that has the objective of bringing together industry end users, resource providers, software providers, and HPC experts.

Simple 2D problem performed with Elmer coupling Navier-Stokes & Heat Equation solvers. Natural convection is taken into account using Boussinesq model.

“With the limits of our current workstations often unable to provide enough memory, simulations taking too long, and the number of jobs too small to get quality results, we are looking for increasing our available computing power beyond our workstations. Should we buy or rent? Buying additional compute power leads us to all kinds of challenges in the context of a high-performance compute cluster acquisition. Now, recently, the other option, renting resources, became more attractive, with the advent of Cloud Computing (http://www.cfdexperiment.com).

The idea of the Experiment is to explore the end-to-end process of remotely accessing HPC resources (read more in this article). Team 30 is formed by:

Industry end-user: Biscarri Consultoria SL
Software providers: Elmer, CAElinux
Resource Provider: Amazon Web Services, CloudBroker

     

The focus of this experiment is to demonstrate the viability of SME’s to perform large CAE simulations using Cloud Computing resources on the net.

Linked Open Data

Interconnecting data, a new revolution of Information Society? Linked Open Data (LOD) is an approach to connect and openly publish related data that was not previously linked and was not previously openly available.

The Web enables us to link related documents and related data. According to the site linkeddata.org,  the term Linked Data refers to a set of best practices for publishing and connecting structured data on the Web. The “Linked Open Data” are published under an open license.  Examples of such data are spatio-temporal, scientific, business and government data.

 

A short and clear explanation about what is LOD and why it is useful to you:

Looking for a Post-processor?

ParaView is an open-source, multi-platform data analysis and visualization application. ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques.

Our favourite Post-processor is by far ParaView, the easy-to-use, good looking, efficient and flexible software initially developed by Kitware Inc. and Los Alamos National Laboratory. ParaView uses the Visualisation Toolkit (VTK) as its data processing and rendering engine and can therefore read any data in VTK format.

Some FEA codes use it as their main post-processing tool. For example, Salome (the Pre- and Post-Processing platform associates to code_aster) has a module called PARAVIS that integrates Paraview. The main post-processing tool provided with OpenFOAM is called paraFoam. It is strictly a script that launches ParaView using the reader module supplied with OpenFOAM.

TED Talks

TED is a nonprofit devoted to Ideas Worth Spreading. The two annual TED conferences bring together the world’s most fascinating thinkers and doers, who are challenged to give the talk of their lives.

You can find many talks related to the fast-growing world of Open Source on TED’s website. Among them, business strategy specialist Don Tapscott gives his “Four principles for the open world”.

Quotes from the talk:

“(…) openness is about sharing (…) IBM gave away 400 million dollars of software to the Linux movement, and that gave them a multi-billion dollar payoff.”

To me, this is not an information age. It’s an age of networked intelligence, it’s an age of vast promise.

Tapscott refers to internet as a “giant global computer“. The expression is especially right if you think that the new version of caelinux – the operating system used by BCSL – has been transferred and adapted to run on Amazon EC2, a cloud computing platform that allows users to rent virtual computers on which to run their own computer applications.

Here’s another talk from Massimo Banzi, co-founder of Arduino, “a tiny, easy-to-use open-source microcontroller that’s inspired thousands of people around the world to make the coolest things they can imagine“.
