Detailed Description

template<class BT>
class Pscf::PolymerTmpl< BT >

Template for an MDE solver and descriptor for a block polymer.

Class template argument BT is an alias for a class that represents a block of a block polymer. By convention, this is a class named Block defined in each implementation-level sub-namespace of Pscf. Each such namespace contains a class named Block that is a subclass of Pscf::Edge, and a class named Polymer that is a subclass of the template instantiation PolymerTmpl<Block>.

A PolymerTmpl<Block> object has an array of Block objects, as well as an array of Vertex objects inherited from the PolymerSpecies base class. Each Block has two Propagator MDE solver objects associated with the two directions along each block.

The solve() member function solves the modified diffusion equation (MDE) for all propagators in the molecule (i.e., all blocks, in both directions) in a pre-defined order.

◆ solve()

template<class BT>
void Pscf::PolymerTmpl< BT >::solve ( double phiTot = 1.0)
virtual

Solve modified diffusion equation for all propagators.

Upon return, all propagators for all blocks, molecular partition function q, phi and mu are all set. The implementation of PolymerTmpl::solve() the calls the solve() function for all propagators in the molecule in a predeternined order, then computes q, and finally computes mu from phi or phi from mu, depending on the ensemble (open or closed) for this species. This solve() function does not compute monomer concentration field.

Each implementation-level namespace defines a concrete subclass of PolymerTmpl<BT> that is named Polymer by convention. Each such Polymer class defines a function named "compute" that takes an array of chemical fields (w-fields) as an argument, and that calls PolymerTmpl<BT>::solve internally. Before calling the solve() function declared here, the Polymer::compute() function must pass pass the w-fields and any other required mutable data to all Block objects in order to set up the MDE solver for each block. After calling the solve() function, the Polymer::compute function must also compute monomer concentrations for all blocks, each of which is stored in a field container owned by the associated Block.

The optional parameter phiTot is only relevant to problems involving a Mask that excludes material from part of the unit cell, as done to define thin film problems.

Parameters
phiTotfraction of unit cell volume occupied by material

◆ propagatorId()

template<class BT>
Pair< int > const & Pscf::PolymerSpecies::propagatorId ( int id) const
inline

Get a propagator identifier, indexed by order of computation.

The return value is a pair of integers that identifies a directed edge, or a propagator. The first integer is a block index between 0 and nBlock - 1, and the second is a propagator direction id, which must be 0 or 1. By convention, direction 0 of Edge i propagates from vertex edge(i).vertexId(0) to vertex edge(i).vertexId(1), while direction 1 propagates in the other direction, from edge(i).vertexId(1) to edge(i).vertexId(0).

The propagators are indexed in an order that is computed by the protected function PolymerSpecies::makePlan. The indexing is chosen such that, if MDEs for different propagators are solved in sequential order by propagator index, then information required to construct the initial condition for the MDE within each propagator (the source slice) is guaranteed to be available from the solution of previous calculations.

Parameters
idpropagator index, in order of computation plan

◆ path()

template<class BT>
Pair< int > const & Pscf::PolymerSpecies::path ( int is,
int it ) const
inline

Get an id for a propagator from one vertex towards a target.

For is != it, the return value is an identifier for an outgoing propagator that begins at the source vertex (vertex index is) and is the first edge of the directed path that leads from the source vertex to the target vertex (vertex id it). The return value is a pair of integers analogous to that returned by the propagatorId(int) member function, for which the first element is a block index and the second element is a direction id (0 or 1) for the propagator direction for that block that is outgoing from from the source vertex along the unique path leading to the target vertex. The requirement that the propagator be outgoing from vertex is implies that if path(is, it) == [ib, id], then edge(ib).vertexId(id) == is.

Parameters
isindex of the source vertex
itindex of the target vertex
