Detailed Description

Mixture of polymers and solvents.

A Mixture contains a list of Polymer and Solvent objects. Each such object can solve the single-molecule statistical mechanics problem for an ideal gas of the associated species in a set of specified chemical potential fields, and thereby compute concentrations and single-molecule partition functions. A Mixture is thus both a chemistry descriptor and an ideal-gas solver.

A Mixture is associated with a Domain object, which models a spatial domain and a spatial discretization. Knowledge of the domain and discretization is needed to solve the ideal-gas problem.

Member Function Documentation

◆ readParameters()

void Pscf::R1d::Mixture::readParameters ( std::istream & in )

virtual

Read all parameters and initialize.

This function reads in a complete description of the chemical composition and structure of all species, as well as the target contour length step size ds.

Parameters

◆ setDomain()

void Pscf::R1d::Mixture::setDomain ( Domain const & domain )

Create an association with the domain and allocate memory.

The domain parameter must have already been initialized, e.g., by reading its parameters from a file, so that the domain dimensions are known on entry.

Parameters

domain associated Domain object (stores address).

◆ setKuhn()

void Pscf::R1d::Mixture::setKuhn	(	int	monomerId,
		double	kuhn )

Reset statistical segment length for one monomer type.

This function resets the kuhn or statistical segment length value for a monomer type, and updates the associcated value in every block of that monomer type.

Parameters

monomerId	monomer type id
kuhn	new value for the statistical segment length

◆ compute()

void Pscf::R1d::Mixture::compute	(	DArray< FieldT > const &	wFields,
		DArray< FieldT > &	cFields )

Compute concentrations.

This function calls the compute function of every molecular species, and then adds the resulting block concentration fields for blocks of each type to compute a total monomer concentration (or volume fraction) for each monomer type. Upon return, values are set for volume fraction and chemical potential (mu) members of each species, and for the concentration fields for each Block and Solvent. The total concentration for each monomer type is returned in the cFields output parameter.

The arrays wFields and cFields must each have size nMonomer(), and contain fields that are indexed by monomer type index.

Parameters

wFields	array of chemical potential fields (input)
cFields	array of monomer concentration fields (output)
