Update the LIGGGHTS

Hi Alice,

Thanks for your kind reply. I type " gedit .git/config" under LIGGGHTS-PUBLIC. In the terminal, it shows
"bash: gedit.git/config: No such file or directory"

I follow the instruction of compiling liggghts and CFDEMcoupling titled "githubAccess_public" and after compiling, when I type the "cfdemTestTUT", error is the same shown as follows:

The version of liggghts is still "LIGGGHTS 1.5.3 based on lammps-10Mar10" and the result of typing "gedit .git/config" is still "bash: gedit.git/config: No such file or directory".

Could you please tell me how to fix this problems? Do I need to reinstall the liggghts and compile again?

Thank you.

Hi Alice,

Also, from the CFDEM Feature, I saw some examples combined with GGI mesh motion, e.g. paddle mixer and ball mill. I would like to do some simulation for rotary dryer combined with fluid flow. So could you please give me some advices, or any tutorial I can learn how to use the GGI mesh motion. I also would like to import my own .stl file as the geometry.

Thank you very much for all the help.
