Detailed Description

Base class for a molecular species (polymer or solvent).

Species is a base class for both polymeric and solvent species descriptors and solvers. Each Species has values of phi, mu and q, and an ensemble enumeration value. The value of either phi or mu must be provided as a parameter in the parameter file, thereby also determining the choice of ensemble. A subclass of Species that actually solves the single single-molecule statistical mechanics problem must use the function setQ(double) to set set the value of the molecular partition function q and to compute a new value for either mu or phi, depending on the ensemble.

Member Function Documentation

◆ readParameters()

void Pscf::Species::readParameters ( std::istream & in )

virtual

Read phi or mu (but not both) and set ensemble accordingly.

This function either reads a value for either phi (species volume fraction) and sets the ensemble to Closed or reads mu (species chemical potential) and sets the ensemble to Open. An Exception is thrown if neither a phi or mu parameter appears in the input stream.

Parameters

in	input stream (parameter file)

Reimplemented from Util::ParamComposite.

Reimplemented in Pscf::PolymerSpecies, Pscf::PolymerTmpl< BT >, Pscf::PolymerTmpl< Block >, Pscf::PolymerTmpl< Block< D > >, and Pscf::SolventSpecies.

◆ setPhi()

void Pscf::Species::setPhi ( double phi )

Set value of phi (volume fraction), if ensemble is closed.

An initial value for phi or mu is normally read from a parameter file. This function is provided for use by a sweep or other procedure in which phi for a species with a closed enesmble is modified after initialization. It is an error to call setPhi for a polymer species with an open ensemble.

Exceptions

Exception if ensemble is open

Parameters

phi	new volume fraction value for this species

Definition at line 43 of file Species.cpp.

References ensemble(), phi(), and UTIL_CHECK.

◆ setMu()

void Pscf::Species::setMu ( double mu )

Set value of mu (chemical potential), if ensemble is closed.

An initial value for phi or mu is normally read from a parameter file. This function is provided for use in a sweep or other procedure in which mu for a species with an open enesmble is modified after initialization. It is an error to call setMu for a polymer species with a closed ensemble.

Exceptions

Exception if ensemble is closed

Parameters

mu	new chemical potential value for this species

Definition at line 54 of file Species.cpp.

References ensemble(), mu(), and UTIL_CHECK.

◆ setQ()

void Pscf::Species::setQ ( double q )

protected

Set q and compute phi or mu (depending on the ensemble).

This function alllows a subclass to set the value of the molecular partition function q, and use this value to compute a corresponding value for either mu (for a closed ensemble) or phi (for an open ensemble). Upon return these variables are related by the equation: \( \phi = \exp(\mu) q \).

Parameters

q	new value of molecular partition function q
