Undrained Triaxial Test

Submitted by greatducks2000 on Thu, 07/16/2015 - 19:08

I need to make a Triaxial Test but am pretty lost on how to fix all the errors I'm getting using LIGGGHTS. I'm running LIGGGHTS through cygwin, and was wondering if someone had already made a triaxial test that I could use. I found one online that I'm getting invalid pair errors for. Thank you very much for help.

The pair error might come from the version of liggghts you used is different from the test example. You could go to the directory of "doc" and check "pair_style" to modify the script commands.

Hi Joshua,

As with other interested individuals, I too would love it if you could share your script at r.a.mukwiri@durham.ac.uk . Am not sure if you have managed to share it for everyone yet.

Kind regards

Hi Jushua,

Thanks in advance. I’m wondering to know if it is possible to share your triaxial script if you still have it.
Your help is highly appreciated. My email is : nima.goudarzi1@northwestern.edu

Many thanks,

If there is so much interest, you may be interested in sharing it with everybody. For instance in the cases-section.

Best wishes

Hello Joshua,

I would like to see how you solve the confining membrane B.C., or did you use bonded particles and somehow convert/equate it to the confining pressure?
If possible, may I also get a copy please?
