Nitin Luhadiya

You can use post-processing software and visualize the trajectory files.

Then you can measure the crack distance for each frame

Long Liu

Dear Nitin Luhadiya

Thanks a lot for your answer. I recently found a way to do it in real time. It is to use the center symmetry parameter to group the atoms, and then the maximum value of the boundary of the atomic group can be used as the length of the crack
