# pair_style hybrid/overlay command

Dear all,
I have a quetion about pair_style hybrid/overlay command. For example:
(1) pair_style hybrid/overlay lj/cut 2.5 coul/long 2.5
(2) pair_style hybrid/overlay lj/cut/coul/long 2.5
(3) pair_style hybrid/overlay lj/cut 2.5 lj/cutc/oul/long 2.5
The effect of these three orders are equivalent ? Thanks!

impossible to say in this generality. whether it is equivalent depends
on the choice of pair_coeff statments and which atoms have charges.

LJ potential and Coulomb forcee can be described by the three forms .Is it right?
After read the manual, I’m a little confused about them. Besides you said just now, what are the differences between them .Thanks!

OK,tank you very much. Now I have an another question about pair_style lj/charmm/coul/charmm command.When I use it to computing the LJ potential and coulomb force,can I use the PPPM solver in long-range Coulomb interaction ? Thanks!

now *i* have a question for *you*: why don't you look it up in the
documentation yourself? if the documentation confuses you, please
explain the confusion and point out the paragraph that is not clear
and how you interpret it. ...and if that doesn't satisfy you: why
don't you make a simple test?

the purpose of this mailing list is for users and developers to help
other users with *real* problems, i.e. problems that cannot be solved
by reading the documentation or making simple experiments. people that
answer questions volunteer their time, so they get easily annoyed, if
confronted with questions that don't need to be asked.

OK，sorry.Thank you! Have a nice weekend!

so if i ask you questions, all i get is "ok, sorry"?
don't you think that is a bit impolite after the many questions of
