[Wien] What is the meaning of GMAX and GMIN

[Torsten Andersen]

Dear Xie,

GMAX is the plane-wave cutoff. It is related to the Bloch functions, and 
need to have a certain minimum value that depends on rmt*kmax. This 
value is calculated during initialization.

Read a book on solid state physics along with the Wien2k users guide - 
that should make it clear.

Best regards,
Torsten Andersen.
