template<typename VECTOR >
void OdeSolution::CalculateDerivedQuantitiesAndParameters ( AbstractParameterisedSystem< VECTOR > *  pOdeSystem)

Calculate the derived quantities and store them and the current parameters for printing/accessing.

Parameters
pOdeSystemthe ODE system which was solved to generate this solution object

std::vector< double > OdeSolution::GetAnyVariable ( const std::string &  rName) const
Returns
the values of a state variable, parameter or derived quantity with a given name in the ODE system for each output timestep.
Parameters
rNamethe name of the variable to extract
