Or just swap...set N's to be the So^2 from a known coordination standard and define an amp for each shell... e.g. So^2 = 0.8 from standard so all N's set to 0.8, and shell 1 had amp1 in the So^2 position defined as guess, shell2 has amp2, etc On 2018-08-01 8:15 AM, Anatoly Frenkel wrote: Ma

Make it 1 in the N window and make amp*N expression in the S02 window instead. Then use N as a coordination number (fix or vary it). Anatoly --- Anatoly I. Frenkel Professor Department of Materials Science and Chemical Engineering Sto

Hello Is there a way in artemis to make N, coordination number, a variable to be used in GDS window? I do realize that N and ss are closely linked and do very similar things in the fit, but it seems i may need fractional (average) coordination number for one of the paths, and am fine fixing ss to s
