Detailed Description

template<unsigned DIM>
class ExtendedBidomainProblem< DIM >

Class which specifies and solves an extended bidomain problem.

See Buist ML, Poh YC. An Extended Bidomain Framework Incorporating Multiple Cell Types. Biophysical Journal, Volume 99, Issue 1, 13-18, 7 July 2010.

Briefly, the problems consits of 3 equations, 2 parabolic and one elliptic. The space is divided in 3 compartments:

  • First cell
  • Second cell
  • Extracellular space.

The three unkowns are the the intracellular potential of the two cells and the extracellular potential. This class allows the user to specify the parameters specific for the these simulations and also different intracellular conductivities for the two cells.

The solution vector used for calculations is arranged as a striped vector with this order:

  • Transmembrane potential of the first cell
  • Transmembrane potential of the second cell
  • Extracellular potential

Unlike a bidomain problem, a node-wise extracellular stimulus can be set up in extended bidomain problems in absence of a bath. This is done by setting a stimulus factory via the method SetExtracellularStimulusFactory. See documentation of AbstractStimulusFactory and ElectrodesStimulusFactory for more details. Note that compatibility conditions will be taken care of by this class by calling specific methods within the stimulus factory class.

void ExtendedBidomainProblem< DIM >::DefineWriterColumns ( bool  extending)
virtual

Define what variables are written to the primary results file. Hardcoded variable names are "V", "V_2" and "Phi_e" for the three variables. If you request any extra variable (via HeartConfig), this method will also define the extra variables by calling a method in the parent class.

Parameters
extendingwhether we are extending an existing results file

template<unsigned DIM>
void ExtendedBidomainProblem< DIM >::ProcessExtracellularStimulus ( )
protected

Small helper tidy-up method that incorporates everything related to the initialisation of the extracellular stimulus.

It checks whether there is any extracellular stimulus, If not, it creates a one (with default implementation to zero stimulus). In any case, it passes the mesh into the stimulus, calls the SetCompatibleExtracellularStimulus method and also checks if there are any grounded nodes. If so, it calls SetFixedExtracellularPotentialNodes.

void ExtendedBidomainProblem< DIM >::SetExtendedBidomainParameters ( double  Am1,
double  Am2,
double  AmGap,
double  Cm1,
double  Cm2,
double  Ggap 
)

Allow the user to specify different values for the bidomain parameters in the extened bidomain framework. This method switches the mUserHasSetBidomainValuesExplicitly to true and tells the problem to overwrite the corresponding parameters in HeartConfig. It needs to be called before Initialise() to have any effect.

Parameters
Am1value of the surface-to-volume ratio for the first cell
Am2value of the surface-to-volume ratio for the second cell
AmGapvalue of the surface-to-volume ratio for the gap junction
Cm1value of the capacitance for the first cell
Cm2value of the capacitance for the second cell
Ggapvalue, in mS of the gap junction conductance

template<unsigned DIM>
void ExtendedBidomainProblem< DIM >::SetExtracellularStimulusFactory ( AbstractStimulusFactory< DIM > *  pFactory)

Sets a stimulus factory as the extracellular one.

Parameters
pFactorythe factory to be set.

Definition at line 224 of file ExtendedBidomainProblem.cpp.

template<unsigned DIM>
void ExtendedBidomainProblem< DIM >::SetFixedExtracellularPotentialNodes ( std::vector< unsigned nodes)

Set the nodes at which phi_e (the extracellular potential) is fixed to zero. This does not necessarily have to be called. If it is not, phi_e is only defined up to a constant.

Parameters
nodesthe nodes to be fixed.
Note
currently, the value of phi_e at the fixed nodes cannot be set to be anything other than zero.
Todo:
turn this into an exception if the user calls this twice...

void ExtendedBidomainProblem< DIM >::SetGgapHeterogeneities ( std::vector< boost::shared_ptr< AbstractChasteRegion< DIM > > > &  rGgapHeterogeneityRegions,
std::vector< double > &  rGgapValues 
)

Set the values of mCellHeterogeneityRegions and mGgapValues for the heterogeneities of Ggap. It just sets the member variables here that will later be passed on to the tissue object. It also checks that the two have the same size. Throws otherwise.

Parameters
rGgapHeterogeneityRegionsa vector of heterogeneity regions for gap junctions
rGgapValuesa vector (of the same size as rGgapHeterogeneityRegions) with the respective values of Ggap for every region.

template<unsigned DIM>
void ExtendedBidomainProblem< DIM >::SetHasBath ( bool  hasBath)

Set whether there is a bath or not. Useful for covering exceptions only (for example if bath problems are not supported and there is no method to analyse the mesh for a bath).

Parameters
hasBathwhether we want the problem to have bath or not.

Definition at line 448 of file ExtendedBidomainProblem.cpp.

template<unsigned DIM>
void ExtendedBidomainProblem< DIM >::SetIntracellularConductivitiesForSecondCell ( c_vector< double, DIM >  conductivities)

Allow the user to specify different values for the conductivities of the second cell type

Parameters
conductivities: the intracellular conductivities of the second cell that you wish to set

Definition at line 272 of file ExtendedBidomainProblem.cpp.

template<unsigned DIM>
void ExtendedBidomainProblem< DIM >::SetNodeForAverageOfPhiZeroed ( unsigned  node)

Set which row of the linear system should be used to enforce the condition that the average of phi_e is zero. If not called, this condition will not be used.

Parameters
nodethe mesh node index giving the row at which to impose the constraint

Definition at line 295 of file ExtendedBidomainProblem.cpp.

template<unsigned DIM>
void ExtendedBidomainProblem< DIM >::WriteInfo ( double  time)
virtual

Print out time and max/min of the intracellular potential of the two cells and phi_e values at current time.

Parameters
timecurrent time.

template<unsigned DIM>
void ExtendedBidomainProblem< DIM >::WriteOneStep ( double  time,
Vec  voltageVec 
)
virtual

Write one timestep of output data to the primary results file. The solution of the problem is in terms of V_1, V_2 and Phi_e (i.e., transmembrane potentials of the two cells plus extracellular potential). It then writes to file V_1, V_2 and Phi_e.

It also writes any extra variable (defined by HeartConfig). Note that it does the job by calling the method in the parent class. This implies that the extra variable must be in the first cell (not the second) because the generic method to write extra variables only looks into the first cell factory. TODO: write a specific method for extended problems that looks in both cell factories

Parameters
timethe current time
voltageVecthe solution vector to write
Todo:
write a specific method for this class
