Dear developers,
I am trying to use the command - group with dynamic region and have questions.
My system has two walls in x-direction and particles between them. While moving one of walls, I want to keep track of all particles with dynamic region keyword.
I am using the version of 30Jul2016.
The result is,
(v_ngas : number of particles defined by the type, v_nbulk : number of particles defined by group - dynamic - region)
(v_locpis3 : location of moving wall - x direction, v_piston : xhi of the region which is used in group-dynamic-region)
Time-averaged data for fix record_3
TimeStep c_mdtemp v_allpress v_allpress2 v_ngas v_nbulk v_locpis3 v_piston

Log file has only warning,
WARNING: One or more dynamic groups may not be updated at correct point in timestep (…/fix_group.cpp:149).
v_ngas and v_nbulk are supposed to be same if it works. I need your help.
