How to add external field using READ_FROM_CUBE subsection ?

[jts2t... at gmail.com]

Hi， Matt,
I know CP2K used multi-grid method to approximate the Gauss function. Did 
you distribute the grid point evenly in the 3-dimentinal space ?  How can I 
get the coordinate of the grid point from the output file of CP2K?

Thanks for your repply !
