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 ne peut pas faire de CAO, ni
de maillage !
On a mis un stagiaire dessus, cela n’a rien donné…
Il n’y a pas d’interface graphique, il faut tout
coder !
Les formats sont incompatibles
avec les logiciels commerciaux !
Au final, ça revient plus cher
que de payer une licence pour
avoir du support…
