How to fix boundary walls
Hi,
I'm carrying out triaxial tests using the script from [1], which uses rigid walls as boundary.
The whole process contains: (a) making sample with target confining pressure and porosity, (b) deviatoric loading.
I'd like to introduce another step for stress relaxation between step (a) and step (b). In this new step, I want to close the triaxial engine and fix all the six walls, and just let the simulation run for some steps with a higher damping coefficient. The way how I fix the walls is by blocking all the degrees of walls, as well as triax.dead=True:
####
triax.wall_
triax.wall_
triax.wall_
triax.wall_
triax.wall_
triax.wall_
triax.dead=True
for i in range(6):
O.bodies[
###
However, I found that in some cases, the size of the sample changes a lot after running for a long time, which means the boundary walls are actually not fully fixed.
Do you have any idea about why this happened?
Thanks
Leonard
