Invalid atom_style command with hybrid

Hi

They updated the LAMMPS version on the cluster in my University from v30Jan14 to stable_17Nov2016 . However, when I run a test file (see below) I get the following error

LAMMPS (17 Nov 2016)

dimension 2

boundary p p p

units si

atom_style hybrid meso bond

ERROR: Invalid atom_style command (…/atom_vec.cpp:71)

The SPH package is installed and the test file works perfectly on my PC (I installed the latest Windows version). Thus, I suppose there is something wrong with the cluster installation. The problem seems to arise with the hybrid atom_style; test cases with only meso work fine.

I know I should probably attach the log files of the installation, but I don’t have those because the update is done centrally. Despite this, I’m wondering if anybody has encounter something similar and has any suggestion/tip?

Best Regards

Alessio

​how about the MOLECULE package? is that installed?
check out the output of ./lmp_mpi -h . does it contain meso and bond under
"* Atom styles:"?
or can you run the "micelle" example with your new executable?​

HI Alex

thanks I will check it. Shouldn’t the MOLECULE package be installed by default?

​depends on where you downloaded the sources.​ "make ps" should tell you
the list of currently installed packages.
