do i understand correctly, that you have never looked into a textbook on
MD? or if you did, that you have forgotten everything?
I am just trying to understand how you made LAMMPS. You are the one who
knows all its secrets. What is sure, is that sarcasms do not need to be
learnt in text books...and often you could keep them for you. When one
writes to this mailing list, he expects some answers or guidance, and not
sarcasms about his knowledge.
this has *nothing* to do with LAMMPS. this is about how MD works at the
very fundamental level. look at how a velocity verlet integrator works (and
that should be shown in any good text book) and you should see the point i
was making. there is no big secret here.
you were simply just repeating what i had explained to you as a question.
that is a waste of your and particularly my time.
just read what you get told more carefully. i have told you multiple times,
that what you are proposing doesn't make sense. that is a strong hint, that
you are about to do something that is not very smart.
when i am withholding details, it is often for a very good reason: this is
something that you should think about and need to understand all the way
through. not to mention. you have heard the saying: give a man a fish and
he is sated for the day, teach him how to fish, and he is sated for the
rest of his life.
well, something similar holds true for science as well. there are topics,
where it is better to make you think and figure it out by yourself. it
sometimes hurts at the beginning, but it pays off big time in the long run.
if it to work, you just have to pay more attention to details and take a
hint here or there. if you expected well formed and ready to consume answer
for even the most fundamental issues of the research you are doing, then
you have to re-think how you learn.
also, you have to realize that this mailing list is a voluntary effort and
you are in no way *entitled* to get any particular level of service here.
when people feel they are being abused, you have to expect some kind of
less helpful reaction. often this is done with the best intentions, as some
people seem to need to feel some level of shame or pain to have their
brains jolted to start thinking in the right way again.
if you ask well formed and meaningful questions, you will get carefully
worded and competent answers. if you ask superfluous questions, you will
either get no answer or something that tries to point out that you have
overstepped the bounds of what is worth asking.
in summary, what you are dealing with here is a quite common phenomenon in
open source software and there are essays like this one
http://www.catb.org/esr/faqs/smart-questions.html that try to explain it.
so get over it, go back and revisit and rethink what you were advised on,
and try to ask smarter questions the next time.
