Bin Flow Tutorial

Submitted by jordantcox on Fri, 12/02/2016 - 20:39

Hello,

I have just installed lights and am working through the tutorial document provided by Chris Stoltz. I was able to download and the tutorial and have double checked with the manual and can't find the error. The error revoles around the particle insertion. Below is the echo, and my code, my code is a copy of the code provided in the tutorials manual.

Any help on this would be much appreciated.

My code:
# Particle Insertion

fix pts all particletemplate/sphere 1 atom_type 1 density constant 1000 &
radius constant 0.0015
fix pdd all particledistribution/discrete 63243 1 pts 1.0
region factory cylinder z 0 0 0.10 0.4 0.41 units box
fix inst all insert/rate/region seed 123481 distributiontemplate pdd &
nparticles 150000 particlerate 150000 insert_every 1000 &
overlapcheck yes vel constant 0. 0. -1.0 region factory ntry_mc 10000

Echo
# Particle Insertion

fix pts all particletemplate/sphere 1 atom_type 1 density constant 1000 radius constant 0.0015
ERROR on proc 0: Random number generation: It is required that the random seed value is > 10000 and a prime number.
The random seed used was 1
Hint 1: start with 'liggghts -echo both < in.script' to find out which command caused this
Hint 2: possible valid seeds would be the following numbers:
15485863, 15485867, 32452843, 32452867, 49979687, 49979693, 67867967, 67867979, 86028121, 86028157 (../random.cpp:69)

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Do as the error message suggests and change
fix pts all particletemplate/sphere 1 atom_type 1 density constant 1000 radius constant 0.0015
to
fix pts all particletemplate/sphere 15485863 atom_type 1 density constant 1000 radius constant 0.0015

Hello,
I am newbie to LIGGGHTS, just performing the tutorial bin flow in which I am facing the error while running

ERROR on proc 0: Cannot open mesh file hopper1.stl (/build/liggghts-QCz4in/liggghts-3.3.1+repack1/src/input_mesh_tri.cpp:100)

please help.
