Detailed Description

Provide the main class for interacting with the System Coupling participant library.

For co-simulation, this class maintains the socket connection to the System Coupling solver. The coupling participant will need to provide host and port information for existing System Coupling server, as well as the name of this coupling participant.

For mapping, an instance of this class should be created to perform mapping.

There should only be one instance of this System Coupling class.

Constructor & Destructor Documentation

◆ SystemCoupling() [1/6]

sysc::SystemCoupling::SystemCoupling ( )

Provide a (default) constructor for the SystemCoupling class for non-cosimulation mode.

This is a default constructor that will initialize the participant library in standalone (non-cosimulation) mode.

When running in parallel MPI environment, the parallel communication within the participant library will use MPI_COMM_WORLD communicator.

◆ SystemCoupling() [2/6]

sysc::SystemCoupling::SystemCoupling ( std::size_t  mpiCommunicator)

Provide a constructor for the SystemCoupling class for non-cosimulation mode with a custom MPI communicator.

Parameters
[in]mpiCommunicatorMPI communicator cast to std::size_t.

This will initialize the participant library in standalone mode and will use the provided MPI communicator for all parallel communication.

◆ SystemCoupling() [3/6]

sysc::SystemCoupling::SystemCoupling ( const ParticipantInfo participantInfo)

Provide a constructor for the SystemCoupling class with a custom struct representing the default input parameters.

Parameters
[in]participantInfoThe struct containing the attributes needed to connect to System Coupling: scHost, scPort, participantName, etc.

◆ SystemCoupling() [4/6]

sysc::SystemCoupling::SystemCoupling ( const ParticipantInfo participantInfo,
std::size_t  mpiCommunicator 
)

Provide a constructor for the SystemCoupling class with an mpiCommunicator object set to non default.

Parameters
[in]participantInfoThe struct containing the attributes needed to connect to System Coupling: scHost, scPort, participantName, etc.
[in]mpiCommunicatorMPI communicator cast to std::size_t.

◆ SystemCoupling() [5/6]

sysc::SystemCoupling::SystemCoupling ( const std::string &  scHost,
const unsigned short  scPort,
const std::string &  participantName,
const std::string &  buildInformation = "Unknown" 
)

Provide a constructor for the SystemCoupling class for cosimulation mode.

Initializes the participant library in cosimulation mode. It establishes the connection to the System Coupling solver.

The participant solver must have obtained the host and port information from System Coupling prior to creating this object (e.g. via an input argument when participant application was started). Copy constructor and assignment operators are disabled to avoid copying the created object.

Parameters
[in]scHostName of the host on which System Coupling is running.
[in]scPortPort number on which System Coupling is listening for participant connections.
[in]participantNameName of this participant (e.g. "MAPDL-1")
[in]buildInformationInformation about the build of this participant solver. This parameter is optional - default is "Unknown".

◆ SystemCoupling() [6/6]

sysc::SystemCoupling::SystemCoupling ( const std::string &  scHost,
const unsigned short  scPort,
const std::string &  participantName,
const std::size_t  mpiCommunicator,
const std::string &  buildInformation 
)

Provide a constructor for the SystemCoupling class for cosimulation mode with a custom MPI communicator.

This constructor works the same way as the one above (see above), but it takes in one additional argument, which is the MPI communicator, cast as std::size_t.

Parameters
[in]scHostName of the host on which System Coupling is running.
[in]scPortPort number on which System Coupling is listening for participant connections.
[in]participantNameName of this participant (e.g. "MAPDL-1")
[in]mpiCommunicatorMPI communicator cast to std::size_t.
[in]buildInformationInformation about the build of this participant solver. This parameter is optional - default is "Unknown".

Member Function Documentation

◆ addCouplingInterface() [1/2]

void sysc::SystemCoupling::addCouplingInterface ( const CouplingInterface couplingInterface)

Provide a function to add a coupling interface.

Parameters
[in]couplingInterface- coupling interface to be added.

Data transfers will be automatically created. If a variable is defined as an output on all regions on one side of the interface and as an input on all regions on the opposite side of the interface, then the data transfer will be added for this variable.

If this coupling interface has already been added, then this call will have no effect.

If a different coupling interface with the same has already been added, then a runtime error will be thrown.

If the coupling interface name contains invalid characters, then a runtime error will be thrown.

See sysc::CouplingInterface for more details.

◆ addCouplingInterface() [2/2]

void sysc::SystemCoupling::addCouplingInterface ( const CouplingInterface couplingInterface,
bool  autoGenerateTransfers 
)

Provide a function to add a coupling interface.

Parameters
[in]couplingInterface- coupling interface to be added.
[in]autoGenerateTransfers- flag whether to automatically create data transfers.

If this coupling interface has already been added, then this call will have no effect.

If a different coupling interface with the same has already been added, then a runtime error will be thrown.

If the coupling interface name contains invalid characters, then a runtime error will be thrown.

If autoGenerateTransfers is true, then the data transfers are generated automatically according to the following rule: if a variable is defined as an output on all regions on one side of the interface and as an input on all regions on the opposite side of the interface, then the data transfer will be added for this variable.

See sysc::CouplingInterface for more details.

◆ addRegion()

void sysc::SystemCoupling::addRegion ( const Region region)

Provide a function to add a region that could be used in a coupled analysis.

Parameters
[in]region- Region to be added.

If this region has already been added, then this call will have no effect.

If a different region with the same has already been added, then a runtime error will be thrown.

If the region name contains invalid characters, then a runtime error will be thrown.

◆ completeSetup()

void sysc::SystemCoupling::completeSetup ( const sysc::SetupInfo setupInfo)

Provide a function to notify System Coupling that setup can be completed.

After this function is called, coupled analysis setup can no longer be updated, i.e. regions and variables cannot be changed. Participant should also pass in sysc::SetupInfo struct to provide additional information about the setup, such as whether steady or transient analysis is to be performed.

Once the setup is complete, any subsequent call to complete the setup will have no effect.

◆ doIteration()

bool sysc::SystemCoupling::doIteration ( )

Provide a function to check whether to do a coupling iteration.

This function returns true if another coupling iteration is required, otherwise it returns false.

◆ doTimeStep()

bool sysc::SystemCoupling::doTimeStep ( )

Provide a function to check whether to do a coupling time step.

This function returns true if another coupling time step is required, otherwise it returns false.

This function should be called to check if another coupling time step should be done. If the previous coupling time step is finished and another time step should be performed, then calling this function will tell System Coupling that the coupling participant is going to advance to the next time step (i.e. calling doTimeStep() will cause doIteration() to change from returning false to returning true, under the conditions described above).

This function only makes sense for transient analysis. It will always return false for steady analysis.

◆ getAddedCouplingInterface()

const CouplingInterface & sysc::SystemCoupling::getAddedCouplingInterface ( std::size_t  index) const

Provide a function to return coupling interface.

Parameters
[in]index- coupling interface index
Returns
Reference to the coupling interface at specified index.

◆ getAddedRegion()

const Region & sysc::SystemCoupling::getAddedRegion ( std::size_t  index) const

Provide a function to return region information.

Parameters
[in]index- region index
Returns
Reference to region information at specified index.

◆ getCurrentTimeStep()

sysc::TimeStep sysc::SystemCoupling::getCurrentTimeStep ( )

Provide a function to get current time step.

Returns
Returns a time step struct, which contains time step number, start time, and time step size for the current coupling time step.

A default value (time step number 0, start time 0.0, time step size 0.0) is returned if this function is called outside the coupled analysis loop or if the analysis is steady.

◆ getNumCouplingInterfaces()

std::size_t sysc::SystemCoupling::getNumCouplingInterfaces ( ) const

Provide a function to return the number of coupling interfaces.

Returns
Number of coupling interfaces.

◆ getNumRegions()

std::size_t sysc::SystemCoupling::getNumRegions ( ) const

Provide a function to return the number of regions.

Returns
Number of regions.

◆ initializeAnalysis()

void sysc::SystemCoupling::initializeAnalysis ( )

Provide a function to notify System Coupling that analysis initialization can be completed.

This function must be called after registering mesh and variable data access and prior to entering the coupled analysis loop.

If this function is called before the coupled analysis is complete, it will automatically complete the coupled analysis and assume steady analysis type.
