To reference an array generated by fix

LAMMPS LAMMPS Mailing List Mirror

Hi,

I am reading example in viscosity calculation via Green-Kubo method.
There are lines that have referenced global array that was result of fix ave/correlation,
say:

variable v11 equal trap(f_SS[3/){scale} variable v22 equal trap(f_SS[4/)*{scale}
variable v33 equal trap(f_SS[5/)${scale}

My question is, where can i find the explanation of the slash followed the array column number?

And I didn’t find explanation about the sequence of output array by fix ave/correlation when there are more than 1 value input, especially for this case in Green-Kubo,
which there are three diagonal stress input.

And an irrelevant question, In the book by J.M.HAILE, Equation 7.69 in page 305 is wrong by putting Volume in denominator, isn’t it?

Thanks

Di

nowhere. they are typos.

Well, f_ss[3] refers to all collomn[3] values, which is the correlation of pxy, and same to f_SS[4] f_SS[5]

Thanks Axel

fixed the typos on the Section howto doc page.
