Our goal: contribute to the use of open source
and free softwares in research and industry

Common ideas about open-source tools
C’est uniquement pour les geeks, sous Linux Si je développe un modèle, je vais être obligé
de le distribuer gratuitement !
Il n’y a pas de documentation, ni de support
Les codes ne sont pas validés
On a mis un stagiaire dessus, cela n’a rien donné…
On ne peut pas faire de CAO, ni de maillage !
Les formats sont incompatibles avec les logiciels commerciaux !
Au final, ça revient plus cher que de payer une licence pour
avoir du support…
Il n’y a pas d’interface graphique, il faut tout coder !

Using open-source sofwtares : pros & cons (our experience)
Select the right toolsAccording to the hardware and users
Integration in your workflows
Skill improvement timeLearn to use the softwares
Adapt your methodologies
No dedicated supportWhere can I find documentation ?
Who can I contact in case of a problem ?
Free licensesCost-killing
Enhance calculation capabilitues
Acces to « massive HPC »
ModularityDepending on the user and its needs
All or part of the simulation workflow
Flexibility/independencyOpen source code
Always available
Keep your own developments
yPlus
We propose a step-by-step process
