[Pw_forum] GW

[Geoffrey Stenuit]

Dear Q J Wang,

It is exactly this.

The general sequence of binaries for computing the GW quasi-particle  
energies is  the
following (in a molecule):
1. pw.x
2. pw4gww.x
3. gww.x

Actually, the pw4gww.x binary will read the prefix.save directory and  
the prefix.wfc
files generated in the first step by pw.x. It is the .save directory  
that control for
example the number of atoms,... for pw4gww.x .

The gww.x binary will then act as a post-processing of pw4gww.x...

This is the overall approach of "how to use this GW code".

Thanks for your remark,

Regards,

Joe
