Detailed Description

An FMI 1.0 co-simulation slave instance.

Member Function Documentation

bool coral::fmi::SlaveInstance1::DoStep ( coral::model::TimePoint  currentT, coral::model::TimeDuration  deltaT  )

overridevirtual

Performs model calculations for the time step which starts at the time point currentT and has a duration of deltaT.

If this is not the first time step, it can be assumed that the previous time step ended at currentT. It can also be assumed that currentT is greater than or equal to the start time, and currentT+deltaT is less than or equal to the stop time, specified in the Setup() call.

Returns

true if the model calculations for the given time step were successfully carried out, or false if they were not because the time step was too long.

Note

Currently, retrying a failed time step is not supported, but this is planned for a future version.

Implements coral::slave::Instance.

bool coral::fmi::SlaveInstance1::GetBooleanVariable ( coral::model::VariableID  variable ) const

overridevirtual

Returns the value of a boolean variable.

bool coral::fmi::SlaveInstance1::SetBooleanVariable ( coral::model::VariableID  variable, bool  value  )

Implements coral::slave::Instance.

bool coral::fmi::SlaveInstance1::SetStringVariable ( coral::model::VariableID  variable, const std::string &  value  )

overridevirtual

Sets the value of a string variable.

Returns

Whether the value was set successfully. This could be false if, for example, the value is out of range.

Exceptions

std::logic_error

Implements coral::slave::Instance.

void coral::fmi::SlaveInstance1::Setup ( const std::string &  slaveName, const std::string &  executionName, coral::model::TimePoint  startTime, coral::model::TimePoint  stopTime, bool  adaptiveStepSize, double  relativeTolerance  )

overridevirtual

Instructs the slave to perform pre-simulation setup and enter initialisation mode.

This function is called when the slave has been added to an execution. The arguments startTime and stopTime represent the time interval inside which the slave's model equations are required to be valid. (In other words, it is guaranteed that DoStep() will never be called with a time point outside this interval.)

Parameters

[in]	slaveName	The name of the slave in the current execution. May be empty if this feature is not used.
[in]	executionName	The name of the current execution. May be empty if this feature is not used.
[in]	startTime	The earliest possible time point for the simulation.
[in]	stopTime	The latest possible time point for the simulation. May be infinity if there is no defined stop time.
[in]	adaptiveStepSize	Whether the step size is being controlled by error estimation.
[in]	relativeTolerance	Only used if adaptiveStepSize == true, and then contains the relative tolerance of the step size controller. The slave may then use this for error estimation in its internal integrator.

Implements coral::slave::Instance.
