VirtualBox is distributed under GNU General Public License (GPL) Version2.

  • Relation between ceenv and MateriApps LIVE!

    MateriApps LIVE! is a VirtualBox virtual machine environment based on ceenv and pre-installed with various computational materials science applications and visualization tools. By simply importing it into VirtualBox, one can immediately start various computational material science simulations, such as first-principles calculations, molecular dynamics, and effective model simulations. All the computational materials science applications included in MateriApps LIVE! have been released as Debian packages, thus one can be easily installed and run on ceenv.
