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).

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“.
