**Glossaries**

This document is incomplete. The external file associated with the glossary 'main' (which should be called energies-511550-addedDoi.gls) hasn't been created.

Check the contents of the file energies-511550-addedDoi.glo. If it's empty, that means you haven't indexed any of your entries in this glossary (using commands like \gls or \glsadd) so this list can't be generated. If the file isn't empty, the document build process hasn't been completed.

If you don't want this glossary, add nomain to your package option list when you load glossaries-extra.sty. For example:

\usepackage[nomain]{glossaries-extra}

> Try one of the following:


makeglossaries-lite.lua "energies-511550-addedDoi"

• Run the external (Perl) application:

> makeglossaries "energies-511550-addedDoi"

Then rerun LATEX on this document.

This message will be removed once the problem has been fixed.
