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:
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.
