restart

hello everyone

I have a simple question: why read_start command cannot be used after a create_box command? It’s all right to be used after a read_data command. In this regard, what’s the difference between defining a box using read_data and create_box command?

best wishes.

hello everyone

I have a simple question: why read_start command cannot be used after a
create_box command?

​because read_restart will need to change settings that can only be changed
before the simulation box is defined and then will also define the
simulation box.​

It's all right to be used after a read_data command.

​that statement cannot be correct for reasons of how LAMMPS works
internally.

In this regard, what's the difference between defining a box using
read_data and create_box command?

​there is none and you *cannot* use read_restart after read_data or after
*any* operation that creates a simulation box unless you use the clear
command which will undo *all* settings including the simulation box.

i challenge you to produce an input that contradicts this statement.
