Generating sample

Asked by Gayanindika on 2011-07-24

I generated a sample using


I need to subject this sample to triaxial shear. But i have a problem about creating the walls (box).

How can I generate the boundary walls to apply the isotropic compression and strain while shear?

If I am to create a facet, at what point I should give the command? (before or after spheres).

If this is not the appropriate command, what is the best command? ( pls give a detailed command. In my sample the initial positions are known. not random)

Thank you.

Hi Gayanindika,

To create the walls around your packing, see the utils function aabbWalls(). Then to apply a triaxial compression, see the engine TriaxialCompressionEngine(). You should have something ressembling those lines in your script to perform what you want:

# defines your assembly

# creates and identifies the walls for the triaxial engine

# defines the triaxial engine (important here to accurately identify the walls)

BTW, there was a triaxial test script in the examples directory... I am not sure anymore since I don't work with the latest version, but maybe you should have a look and ask if needed...



Can you help with this problem?
