Wall disappearing
In the name of God
Hi every one!
I encountered an strange problem. when i add some spheres bonded to each other using CohFrictMat in a triaxial box, by the first step the walls disappeared. what is wrong?
the second strange thing is that although the walls are added to simulation before the definition of material labeled as 'cube', however when the script is run, their material type is shown as 'cube'. here is the MWE:
from yade import pack
