Detailed Description

An ODE system formed by combining several subsystems.

Instances of this class are formed by passing other ODE system instances to our constructor, and then calling Configure to set up any coupling between subsystems. This allows state variables from one system to be used as parameters in other systems.

This allows us to set up coupled systems such as $dy/dt = f(y, t)$ from subsystems $dy_1/dt = f_1(y_1, t; y_2)$ and $dy_2/dt = f_2(y_2, t; y_1)$ where $y = (y_1, y_2)$.

The vector of state variables for the combined system is formed as the concatenation of the state variable vectors of the subsystem. This class also makes use of the CombinedOdeSystemInformation class to provide initial conditions, etc.

Member Function Documentation

◆ Configure()

void CombinedOdeSystem::Configure ( const std::map< unsigned, unsigned > &  rVariableParameterMap,
AbstractOdeSystem pVariableOdeSystem,
AbstractOdeSystem pParameterOdeSystem 
)

Configure a mapping between the state variables of one subsystem and the parameters of another.

Parameters
rVariableParameterMapa map specifying which state variables (keys) are mapped to which parameters (values).
pVariableOdeSystemthe ODE subsystem providing state variable values.
pParameterOdeSystemthe ODE subsystem whose parameters should be set.

◆ EvaluateYDerivatives()

void CombinedOdeSystem::EvaluateYDerivatives ( double  time,
const std::vector< double > &  rY,
std::vector< double > &  rDY 
)
virtual

Evaluate the right-hand side of the combined system.

This calls EvaluateYDerivatives for each subsystem with the appropriate portion of rY and rDY, having set parameters from values in rY according to the configured maps.

Parameters
timethe current time
rYthe current values of the state variables
rDYstorage for the derivatives of the system; will be filled in on return

Implements AbstractOdeSystem.
