Can LIGGGHTS used for two dimensions condtion?

Hi,

Does anybody know if the LIGGGHTS programme can be used in two dimensional conditions? In the source code, somewhere I see it says it is only valid in 3D. How can I do with LIGGGHTS to carry out a 2D biaxial test?

Thanks.

In general there is the

In general there is the possibility to do 2D simulations (see manual) . But some (LIGGGHTS specific) commands will only work in 3D. However, I would recommend you to do a 3D simulation using a thin slice. This will capture the physics much better than 2D and will not cost you much more

2D simulation

Hi Christoph
Actually I am trying to do a 2D simulation from Periodic chanel tutorials in CFDEM. I have done changes in CFD and it work but when I come to the DEM, always I get the error (ERROR: Fix particletemplate/sphere (id pts1): this fix is for 3D simulations only). is there anyway to solve it or you recommend to do a 3D simulation using a thin slice? does it make huge differences in result or it will be acceptable?

Thanks in advance
