Detailed Description

Provide the trace for a transmembrane potential at a single mode of the mesh. File updated during the simulation.

WARNING: If you checkpoint this class then the file output will not be saved in the checkpoint. The state of the output file will be unchanged (up to the most recent file flush) but may be overwritten by a restarted simulation. You will need to manually move the output file before restarting the simulation and then merge the two files together at a later point.

Constructor & Destructor Documentation

SingleTraceOutputModifier::SingleTraceOutputModifier ( )

inlineprivate

Private constructor that resets process-specific data, for archiving

Definition at line 87 of file SingleTraceOutputModifier.hpp.

SingleTraceOutputModifier::SingleTraceOutputModifier ( const std::string &  rFilename, unsigned  globalIndex, double  flushTime = 0.0  )

inline

Constructor

Parameters

globalIndex	The global index of the node which is to be output (assumes no permutation). This is the index *in memory at solve time*. If you are running in parallel and you want a specific location or index in your mesh then you will need to look in the mesh for node or permutation. ChastePoint<1> point(0.05); unsigned new_index_for_5 = mesh.GetNearestNodeIndex(point); SingleTraceOutputModifier("trace_5.txt", new_index_for_5)); or unsigned new_index_for_5 = mesh.rGetNodePermutation()[5]; SingleTraceOutputModifier("trace_5.txt", new_index_for_5));
rFilename	The file which is eventually produced by this modifier
flushTime	The simulation time between manual file flushes (if required)

Member Function Documentation

void SingleTraceOutputModifier::FinaliseAtEnd ( )

virtual

Finalise the modifier (close the file)

Implements AbstractOutputModifier.

Definition at line 57 of file SingleTraceOutputModifier.cpp.

References mFileStream, and mLocalIndex.

void SingleTraceOutputModifier::InitialiseAtStart ( DistributedVectorFactory *  pVectorFactory )

virtual

Initialise the modifier (open the file) when the solve loop is starting.

Note the problem passes parameters in a non-templated fashion in order to keep the interface as lightweight as possible.

Parameters

pVectorFactory

The vector factory which is associated with the calling problem's mesh

Implements AbstractOutputModifier.

Definition at line 41 of file SingleTraceOutputModifier.cpp.

References DistributedVectorFactory::GetLow(), HeartConfig::Instance(), DistributedVectorFactory::IsGlobalIndexLocal(), AbstractOutputModifier::mFilename, mFileStream, mGlobalIndex, mLocalIndex, and OutputFileHandler::OpenOutputFile().

void SingleTraceOutputModifier::ProcessSolutionAtTimeStep ( double  time, Vec  solution, unsigned  problemDim  )

virtual

Process a solution time-step (dump a small line to file)

Parameters

time	The current simulation time
solution	A working copy of the solution at the current time-step. This is the PETSc vector which is distributed across the processes.
problemDim	The calling problem dimension. Used here to avoid probing the size of the solution vector

Implements AbstractOutputModifier.

template<class Archive >

void SingleTraceOutputModifier::serialize ( Archive &  archive, const unsigned int  version  )

inlineprivate

Archive the output modifier, never used directly - boost uses this.

Parameters

archive	the archive
version	the current version of this class

Definition at line 78 of file SingleTraceOutputModifier.hpp.

out_stream SingleTraceOutputModifier::mFileStream

private

Output file stream (remains open during solve).

Referenced by FinaliseAtEnd(), InitialiseAtStart(), and ProcessSolutionAtTimeStep().

unsigned SingleTraceOutputModifier::mGlobalIndex

private

The global index of the node for which the trace is to be made. This is the index *in memory at solve time*. If you are running in parallel and you want a specific index/location in your mesh then you will need to look in the mesh permutation.

unsigned SingleTraceOutputModifier::mLocalIndex

private

The local index of the node for which the trace is to be made - set to UINT_MAX if the node is not local to the process
