[lammps-users] Compute heat/flux command question

Hello, I am running the 7 July 2009 version and attempting to model heat transfer in an LJ fluid box (Ar with Au walls). I am new to LAMMPS. I’ve used the sample code in the users guide for the compute heat/flux and get an error upon execution “requires ghost atoms store velocity”. Doing some research I located and tried to use the communicate command however I continue to get error messages for that command . I believe the problem is that my problem set up employs an atom_style of atomic. The command indicates ghost atom storage only for DPD or granular styles. Referring to the user’s guide I am unable to resolve this. Would someone be able to point me in the proper direction. Thanks very much. Larry Jones
