No I can't - unless you think LAMMPS is doing something
wrong or there is a bug, then I don't have time to help people
figure out how to do simulations correctly.

Thank your review
Hi Xiaoliang,
I assume you use compute heat/flux with Green-Kubo formalism to calculate the thermal conductivity just like the Ar example in the manual. However, Green-Kubo formalism is not suitable for your heterostructures. It is only applicable for homogeneous systems. You should try to use non-equilibrium molecular dynamics method which can be performed with

Thank you!I try to do it in non-equilibrium molecular dynamics method .But i read some article about thermal conductivity in equilibrium molecular dynamics method by Green-Kubo such as
Hi, Xiaopeng
I am interested in the distinction of heterostructures and homogeneous structures. Do the former always have more than one phases while the latter always have only one phase ? Thanks.
Guozhen
No, both are not true. A heterostructure may also only have one phase but with lots of defects, voids, dislocations, serious anisotropic properties, or even just nonuniform density distribution. If you can treat all the areas which are small enough in the structure as the same one, then it is homogeneous.
Regards,
Xiaopeng
