ID = user-assigned name for the dump :ulb,l
|
|
group-ID = ID of the group of atoms to be imaged :l
|
|
adios = style of dump command (other styles {atom} or {cfg} or {dcd} or {xtc} or {xyz} or {local} or {custom} are discussed on the "dump"_dump.html doc page) :l
|
|
N = dump every this many timesteps :l
|
|
file.bp = name of file/stream to write to :l
|
|
args = same options as in "{dump custom}"_dump.html command :l
|
|
:ule

[Examples:]

[Description:]
|
|
|
|
Dump a snapshot of atom coordinates every N timesteps in the
|
|
"ADIOS"_adios based "BP" file format, or using different I/O solutions in ADIOS,
|
|
to a stream that can be read on-line by another program.
|
|
ADIOS-BP files are binary, portable and self-describing.

[Use from write_dump:]
|
|
|
|
It is possible to use these dump styles with the
|
|
"write_dump"_write_dump.html command. In this case, the sub-intervals
|
|
must not be set at all. The write_dump command can be used to
|
|
create a new file at each individual dump.
|
|
|
|
dump 4 all atom/adios 100 dump.bp
|
|
write_dump all atom/adios singledump.bp :pre
|
|
|
|
:line
|
|
|
|
[Restrictions:]
|
|
|
|
The number of atoms per snapshot CAN change with the adios style.
|
|
When using the ADIOS tool 'bpls' to list the content of a .bp file,
|
|
bpls will print {__} for the size of the output table indicating that
|
|
its size is changing every step.
|
|
|
|
The {atom/adios} and {custom/adios} dump styles are part of the USER-ADIOS
|
|
package. They are only enabled if LAMMPS was built with that package.
|
|
See the "Build package"_Build_package.html doc page for more info.
