Dumpfile / Paticle / Time of creation

Submitted by RobertG on Fri, 09/26/2014 - 14:42

Hello,
I'm new at Liggghts. So far I worked with the continuous mixer tutorial.
After a few tries and errors, I managed it, to work under Liggghts 3.0.3.
At the moment I try to get the time of creation of every particle to be written in the dump file.
I searched for some clues, but I didn't find anything.

I hope somebody can help me.

Thanks.
RobertG.

Hi RobertG,

Sorry, but the time of creation is not saved at all. Maybe, a possible workaround is the ID of the particles. In general it is unique and increasing. If you check your dump-files for the first appearance of each ID, you get at least an idea, when they were generated. (E.g. Between dump_2000.liggghts and dump_3000.liggghts) In addition the insertion commands work with an every option. You can adapt your dump command to write a file every time new particles were generated.

Cheers
Andreas

Hi Robert,

>>Sorry, but the time of creation is not saved at all.
This is correct, with one exception: if fix insert/stream is used, there is an internal variable which stores the timestep release of the particles into the simulation
It can be accessed via f_release_fix_insert_stream in a dump command

Best wishes
