Region move command

LAMMPS
1

I want to use region move command for the laser process and I want the region move during simulation with 2.0 angstrom/ps so I used these commands:
variable dx equal 2.0
region laser cylinder z 35 105 25 112 182 move
v_dx NULL NULL units box
but the region didn’t move during the simulation
How can I fix this problem ?
also I located this region in place where atoms are present.

What makes you think that the region did not move?

3

because I used static region and dynamic region and compared results. The results were the same.
also I have spherical particles and I used compute temp for their temperature during the process but during the simulation Their temperature did not rise suddenly.

and I used fix heat command for the melting process:
fix particles heat 1000 270 region laser
particles group is includes all atoms in Spherical particles.

That is not a proof that the region is not moving. You didn’t specify what the “results” are, so I doubt that you will convince someone here that there is an issue with the LAMMPS region command.

I suppose that you gave a static displacement in x direction rather than a time-dependent one.
