Detailed Description

A cardiac cell that is designed to be simulated using CVODE. It uses CVODE's vector type natively via AbstractCvodeSystem.

Functionality is similar to that provided by AbstractCardiacCell and AbstractOdeSystem, but not identical. It also includes a direct interface to the CVODE solver, via the Solve methods, since the CvodeAdaptor class may be a bit slower.

Assumes that it will be solving stiff systems, so uses BDF/Newton.

Various methods in this class just call methods on AbstractCvodeSystem, to reduce compiler confusion when working with things in an inheritance tree.

Any single cell work should generally use this class rather than AbstractCardiacCell.

This class may also be faster for certain tissue problems (especially when using a relatively large PDE timestep (~0.1ms)). BUT it will come with a memory overhead as every node has to carry a CVODE solver object as it stores the internal state of the solver, not just the state variables as ForwardEuler solver does. So may not be appropriate for very large meshes.

Constructor & Destructor Documentation

AbstractCvodeCell::AbstractCvodeCell	(	boost::shared_ptr< AbstractIvpOdeSolver >	pSolver,
		unsigned	numberOfStateVariables,
		unsigned	voltageIndex,
		boost::shared_ptr< AbstractStimulusFunction >	pIntracellularStimulus
	)

Create a new cardiac cell.

Note: subclasses must call Init() in their constructor after setting mpSystemInfo.

Parameters

pSolver	not used for these cells (they're always solved with CVODE); may be empty
numberOfStateVariables	the size of the ODE system modelling this cell
voltageIndex	the index of the transmembrane potential within the vector of state variables
pIntracellularStimulus	the intracellular stimulus current

Definition at line 48 of file AbstractCvodeCell.cpp.

AbstractCvodeCell::~AbstractCvodeCell ( )

virtual

Free the state variables, if they have been set.

Member Function Documentation

OdeSolution AbstractCvodeCell::Compute	(	double	tStart,
		double	tEnd,
		double	tSamp = `0.0`
	)

virtual

Simulates this cell's behaviour between the time interval [tStart, tEnd], and return state variable values.

The maximum time step to use will be taken as mMaxDt. If this is unset it is the same as tSamp, which defaults to HeartConfig::Instance()->GetPrintingTimeStep().

Parameters

tStart	beginning of the time interval to simulate
tEnd	end of the time interval to simulate
tSamp	sampling interval for returned results (defaults to HeartConfig printing time step)

Returns: solution object

rName	variable name
time	the time at which to evaluate variable (only needed for derived quantities).

rParameterName	the parameter name to set the value of,
value	value to set it to.

index	index of the state variable to be set
newValue	new value of the state variable

rName	name of the state variable to be set
newValue	new value of the state variable
