[Yade-users] [Question #690925]: corrupted double-linked list
New question #690925 on Yade:
https://answers.launchpad.net/yade/+question/690925
Hi all,
I am running my Yade model. when the Yade model is small (8000 particles), the
code works well. But when the same model has 100 particles, I get the
following error:
corrupted double-linked list
Aborted (core dumped)
Can anyone help me understand why I get this error? The model compiles well,
but when the first iteration is solved, the error appears.
Thank you for your help.
