problem with "fix thermal/conductivity"

Dear all,

I have a problem with the style of “fix thermal/conductivity”. When I use this command, this error appears: “unknown fix style thermal/conductivity”

I checked the mailing list archive and I found that the problem may be due to the MISC package.
So, I used “make package-status” and I saw that both MISC and USER-MISC packages are installed. what would be my problem then?

Thanks

​having the package installed is only one prerequisite. ​you also have to
have updated your compilation and have to actually use that updated binary.
you can verify that, by looking at the output of ./lmp_mpi -h in your
compilation folder and compare that to the output that you get when you a
-h flag to your simulation run command. also, these days, you have to watch
out for non-ascii characters, e.g. when you cut-n-paste text verbatim from
the manual, as many pdf viewers and webbrowsers have a tendency to replace
certain ascii characters with similar looking non-ascii versions for a more
visually appealing text rendering.

Dear Axel,

Thanks a lot. Actually, after I checked with “lmp_mpi -h”, I understood that I don’t have thermal/conductivity among the fix styles in my compilation folder. I should say that I installed Lammps on my institutional cluster so I cannot update it because of administrative laws. What can I do now to make it work?

Thanks

​there is no alternative to re-compiling LAMMPS.​

Dear Axel ,

Could you please explain with more details what I should do for re-compiling Lammps? Is there anything I could do before making lammps? any change in ./configure? Currently, I installed the 24Jul2017 Development version of lammps from this link:
http://lammps.sandia.gov/download.html
I will be thankful if you can explain what I should do to update this version. Is there any updated source file I can try or any repository, etc?

Regards,

Neda

​everything you are asking about is answered in the LAMMPS manual. there is
no "configure" script for LAMMPS; for most cases "make mpi" or "make
serial" should work out of the box, only in special (documented!) cases or
for enabling additional compile time features, you need to make changes to
makefiles with a text editor.

please note, that in the development version there is a change in the
installation via python convenience scripts (Make.py has been removed and
replaced), that is currently not fully and consistently documented. the
standard "manual" installation is unchanged and works as described.
we expect to have a new stable version released within the next couple of
weeks, as soon as the documentation has been reviewed and​ adjusted for
that and the python convenience scripts properly tested.

Hi -

The documentation for compiling LAMMPS is fairly comprehensive and can be found here:

    http://lammps.sandia.gov/doc/Section_start.html

If you don't have a lot of experience compiling and working with Make files I suggest you find a local expert to help you.
