Revision as of 14:52, 18 January 2012
Authors: Aaron Brown and Jack Maseberg
Goal: We wish to solve the time-dependent Schrodinger equation in 2 dimensions (using gfortran) and plot our still images of the wavefunction with POV-ray to make an animated movie!
Step 1)
Install Xubuntu 11.10 “Oneiric Ocelot” (dual booting: it's easiest to have windows installed and free drive space, then just install Xubuntu onto the free drive space).
Step 2)
Use the Synaptic package manager to install gfortran(4.6.1-9ubuntu3).
Use the Synaptic package manager to instlal povray(3.6.1).
Use the Synaptic package manager to install imagemagick.
Use the Synaptic package manager to install vlc.
Ffmpeg:
sudo wget http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list --output-document=/etc/apt/sources.list.d/medibuntu.list && sudo apt-get -q update && sudo apt-get --yes -q --allow-unauthenticated install medibuntu-keyring && sudo apt-get -q update
sudo apt-get install ffmpeg libavcodec-extra-53
Scripts for making a movie from still photos:
(note-- to make a bash script executable do sudo chmod a+x filename.sh)
