Fmix_LJ::Fmix_LJ ( FluidMixture *  ,
std::shared_ptr< FluidComponent >  fluid1,

)

Add a lennard-jones coupling between two LJ fluid Could set parameters using the Lorentz-Berthelot Mixing Rules if desired

Member Function Documentation

double Fmix_LJ::compute ( const ScalarFieldTildeArray &  Ntilde,
ScalarFieldTildeArray &  Phi_Ntilde 
) const
virtual

Return the interaction free energy given the reciprocal space site densities and accumulate the gradient (functional derivative) w.r.t them in Phi_Ntilde Note that unlike Fex, all site densities are handed to an Fmix and it is Fmix's responsibility to pick up the correct site densities (perhaps using FluidMixture::get_offsetDensity())

Implements Fmix.

double Fmix_LJ::computeUniform ( const std::vector< double > &  N,
std::vector< double > &  Phi_N 
) const
virtual

Return the uniform fluid interaction free energy density given the site densities N and accumulate the derivative w.r.t them in Phi_N. This MUST return the result corresponding to calling compute() with a uniform scalar field. This is called several times during FluidMixture::initialize() to get the desired bulk properties Note that unlike Fex, all site densities are handed to an Fmix and it is Fmix's responsibility to pick up the correct site densities (perhaps using FluidMixture::get_offsetDensity())

Implements Fmix.
