Hi Chandra,

Please always reply to the mailing list as well.
Another question, USER-SMD package requires external library to be installed, have you installed the “Eigen library” ?
For more information, please take a look again at the installation manual for each package requirement.

Dear Emanuel

Sorry I forgot to cc the mailing list.

Yes I did install the ‘eigen library’ for 'USER-SMD.
I followed the exact procedure mentioned in the manual.

Thank you for the help.

Hi Chandra,

I guess it should work well.
Try ‘make clean-all’ and ‘make purge’ before hitting ‘make mpi’

Dear Imanuel

I did ‘make clean-all’ and ‘make purge’ and then ‘make mpi’.
However I am still getting this same error when I run user-smd example.

are you certain, that you are actually using the newly compiled executable?
i see you are not using an absolute path to the lmp_mpi executable,
but have it looked up via $PATH
so did you copy a previously compiled executable to a folder in $PATH?

axel.

Dear Axel

Thank you very much.
I just used the actual path to ‘lammps/src/lmp_mpi’ and it works.

Thank you so much again.

Chandra
