Invalid pair style foe colloid potential

LAMMPS LAMMPS Mailing List Mirror

dear all,

I have been trying to run the example named in.colloid in the lammps package, howerver, there is always an ERROR: Invalid pair style(force.cpp:168).

my lammps vession is :lammps-11Jul13.

I have compiled the colloid package as the manual says, it didn’t work.

What can I do to solve this problem?

Below is the code which I didn’t change anything:

colloid potential

pair_style colloid 12.5
pair_coeff 1 1 1.0 1.0 5.0 5.0 12.5
pair_coeff 1 2 5.0 1.0 5.0 0.0 7.0
pair_coeff 2 2 10.0 1.0 0.0 0.0 2.5

dear all,

there are two possible options.
a) despite what you are saying, your executable does not contain the
colloid pair style. this can be easily verified by using the -h switch
as this will list all compiled in styles.

b) your text is using non-ascii characters (e.g. as blanks) which is
not supported.
