Regarding using COLLOID Package

Dear user,

I have installed all the available packages in LAMMPS 2015 version.But when I was running a program given in examples i.e for a COLLOID it shows the following error.

[email protected]…5755…:~/Desktop/lammps-10Aug15/examples/colloid$ …/…/src/lmp_serial<in.colloid
LAMMPS (10 Aug 2015)
Lattice spacing in x,y,z = 10 10 10
Created orthogonal box = (0 0 -5) to (300 300 5)
1 by 1 by 1 MPI processor grid
Created 900 atoms
Setting atom values …
861 settings made for type/fraction
Setting atom values …
39 settings made for mass
Setting atom values …
861 settings made for mass
ERROR: Unknown pair style (…/force.cpp:183)

I have installed the colloid package.But then also the above error is coming

Can anybody tell me how to deal with this problem.

With Regards,

​you say you installed the package, but you didn't say whether you did this
before or after you compiled LAMMPS (it has to be before).
you can easily verify, if a pair style is installed by running
./lmp_serial -h

if you get "unknown xxx style" errors, there are three principle origins:
- the style is indeed not compiled into the executable
- you have a typo in your input
- your input contains non-ascii characters (e.g. due to using cut-n-paste
with non-ascii encodings) that look like their ascii counterparts (e.g.
blanks).
