Hi Ye Wenxiang,

fracextract has two output options, the default is a text file and the other is a VTK file. To output fractures in VTK format, add the -vtk keyword to the fracextract command. Something like this will work:

fracextract -i snapshot -o fractures.vtu -vtk -t 0 10 100

You can then import the VTK file into Paraview for visualisation. The fractures.vtu file only contains point data. Each datapoint represents the location of a broken beam interaction. The time of fracture, beam radius and direction of the beam (its normal) are also recorded. I typically visualise fractures using a "line" glyph. I set the orientation of the line to be equal to "normal" and its length equal to "radius".

I hope this helps.

Cheers,

Dion
