Oscillating box of granular with LIGGGHTS

Submitted by m.farahani on Thu, 08/28/2014 - 14:55

Hello ,

I am new user for LIGGGHTS. I'd like to simulate an oscillating box which has granular material in it.

I can create my particles,but I can not oscillate my box. The only useful command which I find is :

fix ID group-ID wall/gran model_keyword model_values wallstyle wallstyleargs general_keywords general

Here I can move the wall with using shear which is not useful for me.

Hope that you can help me.

Best regards,
Mohammad Farahani

Sorry, I think I have solved the problem other way.
Firstly, I define my geometry in CAD software (in my case it was FreeCAD ) then I export the ASCII STL version.
After that I use mesh/surf (to import my geometry) and move/mesh(to wiggle it) command.
