This page contains the runlevels for the new yambo beta version 3.4.0 released under GPL.
For versions up to 3.3.0 check here: old runlevels.


What do you want yambo to calculate? Specify your choice by passing to yambo the command line options corresponding to the required runlevels. Here you will find a brief description of each runlevel. For the input variables connected to each runlevel please visit the Input file section. For the theoretical background connected please visit the Documentation section.

Runlevel combinations

In practice, it is often better to activate several runlevels at the same time by specifying a combination of command line options. Some standard examples are given below. However, we strongly suggest that you follow the tutorials to learn how to use yambo properly and combine the runlevels correctly.
