[Pw_forum] Basis sets (plane wave)

[Robert Hembree]

Getting the expansion coefficients isn’t very difficult. I found the easiest way for me was to use pw_export.x and then look at the resulting xml file. If you dig through the pw_export.x code you can work out how to access them more directly.

Dear Axel,

Thanks for reply.

You are right. So I should search for the expansion coefficients in the output file, right?

How can I find them in the output file?

There is/are no such file(s). There is no need. The basis sets are uniquely defined by the energy cutoff.
