+
+The frequency and format of thermodynamic output is set by the

+"thermo_style"_themo_style.html command also specifies what values are

+(e.g. press, etotal, etc) which include time-averaged versions of

+
+In LAMMPS, a "compute"_compute.html comes in two flavors: ones that

+Input script variables of various kinds are defined by the
+"variable"_variable.html command. All kinds except the atom-style

+quantities (mass(), vcm(), etc), references to thermodynamic
+quantities (e.g. temp, volume, etc), or references to other variables
+or "computes"_compute.html. Thus a variable is the most general way
+to define some quantity you want calculated and output with
+thermodynamic info.
+
+Dump file output is specified by the "dump"_dump.html and
+"dump_modify"_dump_modify.html commands. There are several
+pre-defined formats (dump atom, dump xtc, etc). There is also a "dump
