<P><B>Description:</B>
</P>
<P>Fix <I>eos/cv</I> applies a mesoparticle equation of state to relate the
particle internal energy (u_i) to the particle internal temperature
(dpdTheta_i). The <I>eos/cv</I> mesoparticle equation of state requires
the constant-volume heat capacity, and is defined as follows:
</P>
<CENTER><IMG SRC = "Eqs/fix_eos-cv.jpg">
</CENTER>
<P>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.
