Hello,

I tried to calculate Madelung potential, but no output appeared.
In the past, I succeeded in calculation of Madelung potential in above way. 
But I failed today using the latest version of VESTA.

What I did is 
Utilities  --> Site Potentials and Madelung Energy
Enter 0.9Å for Radius of ionic sphere 
Enter 3Å for Reciprocal-space range

I really want to get site potential of my compound.
Does anybody knows how to solve this?

Best,
Daichi


One of the cif file I used for the calculation is as follows;
