How to simulate an oedometer test?

Submitted by faat1107 on Mon, 02/27/2012 - 12:03

I am a beginner of liggghts and need to make a simulation of oedometer test which is a one-dimensional test and the clay sample is immersed in water, the top wall and bottom wall allow the passage of water during consolidation. The followings are my questions :

1. Should there be two types of particles , one is the clay particle and the other one is water particle?
2. How can I create the wall which allow the passage of water particles but not for clay particles?
3. Could anyone send me example of the script of simulation of oedometer test?

Many thanks!!

Hi Faat,

>>1. Should there be two types of particles , one is the clay particle and the other one is water particle?
that would be an idea - however, you would have to implement SPH-granular interaction for that

>>2. How can I create the wall which allow the passage of water particles but not for clay particles?
you can control that by creating two particles groups and using only one of them as fix group for the wall

>>3. Could anyone send me example of the script of simulation of oedometer test?
I don't think anybody in the forum will do your work for you :-)

Thank you very much for your reply!
I would like to ask one more question, if there are clay particles and water particles in my simulation, the atomic style should be: granular? molecular? or hybrid granular molecular? or any other?

Thanks
