Hi all,
I used ''FFTSG LIBRARY'' and ''WAVELET'' to calculated the electron
density of a slab (PERIODIC XZ; lattice: ABC 10.089 25.0 10.089). And
the code gives the following error, could anyone tell me how to deal
with it? Thanks a lot.

 Value of     2 not allowed for fft, allowed values are:

BTW, is it suitable using FFTW LIBRARY instead to calculated the
electron density of a slab?

Best regards,
