Dear all,
Just running a simple test, when I tried to run the below code with the latest LAMMPS version (11Nov13), the simulation was terminated by the: ERROR: Invalid fix style (…/modify.cpp:714). This error is related with the command: fix 1 sample rigid single. However, with an older LAMMPS version (15Jan10) the same code run well. The detailed running process can be found in attached document. Therefore, I am wondering is there a bug with the fix rigid command for the latest LAMMPS version, or there is something wrong within my code? Thanks.
Best regards,
Junjie
