[lammps-users] tilt factors for triclinic domain

Dear users,

I want to simulate the parallelepiped, and in data.file I used:
0 10 10 xlo xhi
0 10 10 ylo yhi
0 10 10 zlo zhi
5 0 0 xy xz yz
but after running, it reports:"Unknown identifier in data file: 5 0 0
xy xz yz"

I don,t know where is the pronlem/

I even try to run the examples of lammps, and modifed the data.file of
peptide as follow:

36.840194 64.211560 xlo xhi
41.013691 68.385058 ylo yhi
29.768095 57.139462 zlo zhi
0.0 0.0 0.0 xy xz yz

but it also reports::"Unknown identifier in data file: 0.0 0.0 0.0 xy
xz yz"
if the line"0.0 0.0 0.0 xy xz yz" is deleted, it runs very well.

Regards,

Are you running the current version of LAMMPS?
Are there extra spaces in xy xz yz?
Try adding the line

0 0 0 xy xz yz

to bench/data.chain and running in.chain. It works
fine for me.
