Of course one can use U and J, instead of an U_eff ~ U-J.
But then you have 2 parameters ....

Please restrict J to physical meaningful values (~ 1 eV).

Hi,

I m working on some correlated system based on iron, and I m varying the
U with the SIC approximation.

As I see the J is taken always 0,and Ueff equal to the U we take, but in
the first test I did : if we take the same U with different J ,the
results will be different (especially the magnetic moment and the
orbital moment). Did that mean that the code read the J in some subroutines.

Note:I didn't change any thing in the calculation,just the J,all the
others (kpionts,rkmax....) are the same.
