Hi,
When I compute the interaction energy(LJ potential) with hybrid lj/cut and airebo, the newest lammps (10 Nov 2010) returns “ERROR: Pair hybrid sub-style does not support single call”. But that input file works fine with 2010-08-25 version.
What’s wrong with my input?
The related code as follows
pair_style hybrid/overlay lj/cut 10 airebo 3.0 0 0
pair_coeff * * airebo CH.airebo C C
pair_coeff 1 2 lj/cut 0.00373 3.400
compute 1 fix1 group/group fix2
variable E_vdw equal c_1
thermo_style custom step v_E_vdw

you cannot do a group/group compute with a many-body potential.

hi, axel
Steve had modified the code to make it work,
more details see [http://lammps.sandia.gov/threads/msg14701.html](http://lammps.sandia.gov/threads/msg14701.html).
But when I update to the newest code, it returns that error.
I have no idea how to modify these codes.
Thank you!

in the mail he writes clearly that group/group between
airebo is not supported. since you are using hybrid/overlay
airebo will be called, i.e. it is not supported.
But when I update to the newest code, it returns that error.
I have no idea how to modify these codes.
tough luck.

Axel,
Sorry, it’s my fault.
I should use “pair_style hybrid lj/cut 10 airebo 3.0 0 0” , not hybrid/overlay.
Thank you for your help!
