[CP2K-user] How to obtain a denser grid mesh for electron density cube file?

[Kaixuan Chen]

Dear All,

I am using CP2K to produce electron density cube file based on the setting 
of (CP2K_INPUT <https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT.html> / 
FORCE_EVAL 
<https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT/FORCE_EVAL.html> / DFT 
<https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT/FORCE_EVAL/DFT.html> / 
PRINT 
<https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT/FORCE_EVAL/DFT/PRINT.html> 
/ E_DENSITY_CUBE 
<https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT/FORCE_EVAL/DFT/PRINT/E_DENSITY_CUBE.html>
). 
I have already set the STRIDE 
<https://manual.cp2k.org/cp2k-8_1-branch/CP2K_INPUT/FORCE_EVAL/DFT/PRINT/E_DENSITY_CUBE.html#list_STRIDE> 
to 1, but still the grid mesh is too coarse. Is there any other parameter 
that could be used to obtain a denser grid mesh of electron density?
Thank you for any suggestions.

Best,
Kai
