Detailed Description

template<int D, class PT, class ST>
class Pscf::Prdc::MixtureReal< D, PT, ST >

Solver and descriptor for a mixture of polymers and solvents.

A MixtureReal contains lists of Polymer (PT) and Solvent (ST) objects. Each such object can solve statistical mechanics of a single molecule of the associated species in a set of specified chemical potential fields, and thereby compute concentrations and molecular partition functions for all species in non-interacting reference system.

The compute() member function computes single-molecule partition functions and monomer concentrations all species. This function takes an array of chemical potential fields (w fields) acting on different monomer types an input and yields an array of total monomer concentration fields (c fields) as an output.

◆ readParameters()

template<int D, class PT, class ST>
void Pscf::Prdc::MixtureReal< D, PT, ST >::readParameters ( std::istream & in)
virtual

Read all parameters and initialize.

This function reads in a complete description of the structure of all species and the composition of the mixture, plus a few other parameters.

Parameters
ininput parameter stream

◆ associate()

template<int D, class PT, class ST>
void Pscf::Prdc::MixtureReal< D, PT, ST >::associate ( Mesh< D > const & mesh,
FFTT const & fft,
UnitCell< D > const & cell,
WaveListT & waveList )

Create associations with Mesh, FFT, UnitCell, and WaveList objects.

The Mesh<D> object must have already been initialized, e.g., by reading the dimensions from a file, so that the mesh dimensions are known on entry. The FFTT object must have been set up with mesh dimensions equal to those of the mesh. The UnitCell<D> must have been assigned a non-null lattice system, but does not need to have initialized lattice parameters.

This function is called within the readParameters function of the parent System, after calls to the readParameters member functions of the Mixture and Domain. The Mesh, FFT, and UnitCell lattice are initialized by the Domain readParameters function prior to entry.

Parameters
meshassociated Mesh<D> object
fftassociated FFTT object (Fast Fourier Transform type)
cellassociated UnitCell<D> object
waveListassociated WaveListT object

◆ setFieldIo()

template<int D, class PT, class ST>
void Pscf::Prdc::MixtureReal< D, PT, ST >::setFieldIo ( FieldIoT const & fieldIo)

Create an association with a FieldIoT object.

The associated FieldIoT is only used by member functions that write concentration or propagator fields to file.

Parameters
fieldIoassociated FieldIoT object

References fieldIo().

◆ allocate()

template<int D, class PT, class ST>
void Pscf::Prdc::MixtureReal< D, PT, ST >::allocate ( )

Allocate required internal memory for all solvers.

This function is called within the readParameters of the parent System, after the associate() function.

References nMonomer(), nPolymer(), nSolvent(), and UTIL_CHECK.

◆ compute()

template<int D, class PT, class ST>
void Pscf::Prdc::MixtureReal< D, PT, ST >::compute ( DArray< FieldT > const & wFields,
DArray< FieldT > & cFields,
double phiTot = 1.0 )

Compute partition functions and 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 (phi) 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 function parameter. Monomer concentration fields are normalized by the inverse steric volume per monomer in an incompressible mixture, and are thus also volume fractions.

The array function parameters wFields and cFields must each have capacity nMonomer(), and contain fields that are indexed by monomer type index.

The optional parameter phiTot is only relevant to problems such as thin films in which the material is excluded from part of the unit cell by imposing an inhomogeneous constraint on the sum of monomer concentrations, (i.e., a "mask"). In such cases, the volume fraction phi for each species is defined as a fraction of the volume that is occupied by material, rather than as a fraction of the entire unit cell volume.

This function does not compute SCFT free energies or stress (i.e., derivatives of free energy with respect to unit cell parameters).

Parameters
wFieldsarray of chemical potential fields (input)
cFieldsarray of monomer concentration fields (output)
phiTotvolume fraction of unit cell occupied by material

◆ setIsSymmetric()

template<int D, class PT, class ST>
void Pscf::Prdc::MixtureReal< D, PT, ST >::setIsSymmetric ( bool isSymmetric)

Set the isSymmetric flag true or false.

The isSymmetric variable affects whether a space group is written in field file headers by functions that write concentration or propagator fields to file. This variable should be set true after calling compute if the w fields passed to the compute function were known to be symmetric under the space group.

Definition at line 262 of file MixtureReal.tpp.

◆ computeStress()

template<int D, class PT, class ST>
void Pscf::Prdc::MixtureReal< D, PT, ST >::computeStress ( double phiTot = 1.0)

Compute derivatives of free energy w/ respect to cell parameters.

The optional parameter phiTot is only relevant to problems with a mask, in which the material is excluded from part of the unit cell by imposing an inhomogeneous constrain on the sum of monomer concentrations. In such cases, the stress needs to be scaled by a factor of 1/phiTot.

Parameters
phiTotvolume fraction of unit cell occupied by material

◆ createBlockCRGrid()

template<int D, class PT, class ST>
void Pscf::Prdc::MixtureReal< D, PT, ST >::createBlockCRGrid ( DArray< FieldT > & blockCFields) const

Get c-fields for all blocks and solvents as array of r-grid fields.

On return, each element of the blockCFields array contains the monomer concentration field for a single block of a polymer species or a single solvent species. These are indexed with polymer blocks first, followed by solvent species. Polymer blocks are listed with blocks of each polymer placed consecutively in order of block index, with polymers ordered by polymer index. Fields associated with solvents are listed after all polymer blocks, ordered by solvent species index.

This function will allocate the blockCFields array and the FieldT arrays it contains as needed. This array thus does not need to be allocated on entry. If the array or the fields objects it contains are allocated on entry, their capacities must be correct or an error will be thrown.

Parameters
blockCFieldsDArray of FieldT field objects (output)

◆ writeQAll()

template<int D, class PT, class ST>
void Pscf::Prdc::MixtureReal< D, PT, ST >::writeQAll ( std::string const & basename)

Write all propagators of all blocks, each to a separate file.

Write all propagators for both directions for all blocks of all polymers, with each propagator in a separate file. The function writeQ is called internally for each propagator, and is passed an automatically generated file name. The file name for each propagator is given by a string of the form (basename)_(ip)_(ib)_(id), where (basename) denotes the value of the std::string function parameter basename, and where (ip), (ib), and (id) denote the string representations of a polymer indiex ip, a block index ib, and direction index id, with id = 0 or 1. For example, if basename == "out/q", then the file name of the propagator for direction 1 of block 2 of polymer 0 would be "out/q_0_2_1".

Parameters
basenamecommon prefix for output file names
