Problem with WAVELET Poisson solver for periodic 2D systems

[Riccardo Pezzetta]

Dear CP2K community,
I used the Poisson solver WAVELET, with PERIODIC XY and I wrote  PREFERRED_FFT_LIBRARY FFTSG in the GLOBAL section. I am using the last version of CP2K (2026.1), but still it does not work and in the output I see 
"Poisson solver for this periodicity not yet implemented".

I have attached my input in the email. Can someone explain me why it does not work please? Thank you in advance.

Best regards,

Riccardo Pezzetta

Hi，

The latest version after 2026.1 has supported your need.

Best regards，

Xuan
