Visualization of Phonon modes

Dear Abinit users,

Can someone help me with the visualization of eigenvectors at Gamma-point after anaddb? I have installed agate but don’t know how to visualize the modes.

Dear koyendrila,

With agate, you can open the output of anaddb (.nc file or ddb file) and analyze it:

  • type agate in the terminal
  • in agate type :o $NameofYourFile to open the file
  • then type :m ph for phonon mode
  • finally type :add 0 0 0 1 to visualize the first mode at gamma.

If you want to visualize all the modes you can type :add qx qy qz all

There is also a basic help when you type :h in agate.

Best,

Louis
