Fracextract file

Asked by Piotr Klejment on 2018-03-29

Hi!

I created a file with a command:
fracextract -i snapshot -o fractures.txt -rot -t 0 401 5000

In the file "fractures.txt" I see ten different columns of numbers. Could you explain what every column mean?

Thank you!

Each line in the file shows the data of one bond broken during the time span given by -t

The columns are:

pos_x pos_y pos_z rad time dir_x dir_y dir_z id1 id2

where

pos_x pos_y pos_z is the position of the bond before breaking, i.e. the point where the particles interact
rad is the radius of the broken bond
time is the time _step_ of the snapshot before which the bond was broken (i.e. the time resolution of fracextract is the number of time steps between snapshots!)
dir_x dir_y dir_z is the orientation of the broken bond
id1 id2 are the ids of the particles which where connected by the bond before breaking.

Hello!

Could You also describe the file generated by grainextract command?

Thank You!

Hi Glaubiger,

I will answer this in a new thread as grainextract is a quite different tool to fracextract.

Cheers,

Dion
