[lammps-users] formulation of heat current and usage of per atom stress

Dear Alper and Xiaoliang,

You are right. Only the virial part from stress/atom should be used in
the flux calculation.
This can be done by appending the virial keyword to the stress/atom compute.

Dear Steve,
Could you please append the virial keyword in the example
compute myStress all stress/atom virial

Sorry for overlooking (yet another) mistake in the doc page.

Best,
Mario

As Alper Kinaci said,

compute myKE all ke/atom
compute myPE all pe/atom
compute myStress all stress/atom
compute flux all heat/flux myKE myPE myStress

maybe should be

compute myKE all ke/atom
compute myPE all pe/atom
compute myStress all stress/atom virial
compute flux all heat/flux myKE myPE myStress

As in the command "compute stress/atom", the virial keyword means
include all terms except the kinetic energy ke.
And while computing heat flux , we need not the kinetic term for
stress calculation.

Done.
