how to remove a wall

Submitted by adabubu on Wed, 03/30/2011 - 12:17

Hello, Christoph, i simulated a compression test, after compression, i want to remove the top plane. As i understand, it could be done by using unfix wall and i used unfix wall/gran/hertz/history, but i got 'Segmentation fault', could you help me? By the way, i used the latest version of LIGGGHTS.

P.S. I have read few similar discussions in the forums. Based on these discussions, the bug should be fixed, so i don't know if something i did wrong.

thanks,

Ada

do you have more backtrace? Because from this one cannot see much.
If not, please send me the example per mail.

Thanks, Christoph

from the example I can see that you unfixed the mesh - instead you have to unfix the fix wall/gran...

best,
