OK...except the finite SH harmonic expansion suffers from aliasing, so (0,0) changes. I did a quick check and the default (14) is about 1E-6 off whereas going up to 31 was about converged to about 1E-7. On Wed, May 3, 2017 at 8:45 AM, Peter Blaha wrote: > Remember, in output0grr we calculate just

Remember, in output0grr we calculate just the average of grad rho / rho For this average inside the sphere, only the lm=0 term is essential, non-spherical terms of the fit of grad rho/rho do not enter. On 05/03/2017 03:39 PM, Laurence Marks wrote: I just had a look at *.output*grr* for an mBJ

[Wien] XC fit for mBJ

I just had a look at *.output*grr* for an mBJ case, and noticed that the XC fit is best described as awful. Has anyone investigated whether, similar to -eece, a much larger spherical harmonic expansion should be used. Maybe it does not matter. -- Professor Laurence Marks "Research is to see what
