Dear LAMMPS users ,
I need to use electric field with two different ways on my system , one is pulsed electric field and another is electric field from two different directions alternatively.
Is it possible with LAMMPS ?
Thanks for your attention .
Best,
Saeed.

This is a superfluous question. What is possible in lammps is described in the manual. Have a good look. But before you do that, I suggest you try to figure out, what a reasonable physical model for your desired simulation is.

Dear Axel ,
I want to use this technique for separating two particle from each other in
my system and I believe it is reasonable !
Unfortunately I could not find in " fix efield " 's document anything about
that so I just wanted to make sure !
I am sorry If you believe it was superfluous question .
Thanks for your attention.

To separate two particles in a simulation, you can simply add a force.
Unfortunately I could not find in " fix efield " 's document anything about that so I just wanted to make sure !
So why don’t you say so?
I am sorry If you believe it was superfluous question .
It certainly was a badly posed question.
You still haven’t described the physical model that you want to implement.
What your personal feelings about this are is of no relevance. You have either provide precedence or a convincing derivation.

after double checking with the fix efield documentation, i wonder how
you can come to this conclusion. fix efield allows the field vector
components to be given as a variable. thus it only requires to define
a suitable equal style variable depending on the simulation time
(step). so all you ask for can be easily done.
like i mentioned before, you first have to break down what you want to
do into its actual physical model, and you will more easily find what
you are looking for. many of the tools in LAMMPS can be used in many
more ways than what is explicitly spelled out in the documentation. it
is a mistake to expect the documentation to have problem solution
strategies for the huge number of possible applications mapped out.
I am sorry If you believe it was superfluous question .
i think i have just proven it. 
Dear Axel ,
You are right .
Thank you so much for your time.
