fix eos/cv command :h3
|
|
|
|
[Syntax:]
|
|
|
|
fix ID group-ID eos/cv cv :pre
|
|
|
|
ID, group-ID are documented in "fix"_fix.html command
|
|
eos/cv = style name of this fix command
|
|
cv = constant-volume heat capacity (energy/temperature units) :ul
|
|
|
|
[Examples:]
|
|
|
|
fix 1 all eos/cv 0.01 :pre
|
|
|
|
[Description:]
|
|
|
|
Fix {eos/cv} applies a mesoparticle equation of state to relate the
|
|
particle internal energy (u_i) to the particle internal temperature
|
|
(dpdTheta_i). The {eos/cv} mesoparticle equation of state requires
|
|
the constant-volume heat capacity, and is defined as follows:
|
|
|
|
:c,image(Eqs/fix_eos-cv.jpg)
|
|
|
|
where Cv is the constant-volume heat capacity, u_cond is the internal
|
|
conductive energy, and u_mech is the internal mechanical energy. Note
|
|
that alternative definitions of the mesoparticle equation of state are
|
|
possible.

|
The fix {eos/cv} is only available if LAMMPS is built with the
|
|
USER-DPD package.
