Hi there,
corresponding to the official System Coupling pdf by Ansys, I tried to setup my own 2way FSI. Fluent and Mechanical can solve their own parts, but in the FSI it seems that they dont communicate via system coupling. What does the following message mean? Btw, I have no further output  __________________________________________________ ______________________ +================================================= ===================+ | Setup Validation | +================================================= ===================+ No warnings or errors. DBG | Starting RPC server... DBG | Registering cosimulation participants... DBG | Writing SCS file... DBG | Waiting for expected service provider connections from: DBG | * Solution 7 DBG | * Solution 5 DBG | Before serve one request for connections... DBG | Request served - Scanning to see if all required service providers have been registered... DBG | Before serve one request for connections... DBG | _RPCRegisterServiceProvider called from DBG | (Name, Host, Port): (Solution 5, *computer*, 49294) DBG | Request served - Scanning to see if all required service providers have been registered... DBG | Last provider to connect: Solution 5 DBG | Before serve one request for connections... DBG | DBG | Stop file found... DBG | Code : 2 DBG | Message: System coupling run aborted by user: A solver failure occurred during the run in the system. DBG | Connecting to service provider: Solution 5 +================================================= ===================+ | System Coupling Co-Simulation Summary | +================================================= ===================+ Participant : Solution 5 Version/Build Info = 14.0.0 DBG | Disconnected service provider: Solution 5 System coupling run completed with errors. __________________________________________________ ______________________ |

its a weird failure...
It helped to remove+recreate the "system coupling" part in the workbench. Now, it runs through the Setup Validation and System Coupling Co-Simulation Summary, but crashes there with: System Coupling Exception Origin Fluent Error Code 20 Description: ... coupling requested ChartableData-> GetRootLevelName: communication socket unexpectedly disconnected *** FATAL *** CP = 2.524 TIME= 15:37:24 The system coupling service error notification: Exception originated from the noted participant when the coupling service requested ChartableData->GetRootLevelName: Communication socket unexpectedly disconnected.

Hi,
I am doing a similar setup for FSI but I receive the following error message. " The system coupling service error notification: Duplicate service provider - disconnected" I have checked the license preferences and they are using separate license for each application. Can anyone guide me with this ? ¬Awais |

Additionnal information  reconditioned conjugate gradient solver error-level 1-possibly,the model is unconstrained or additional iterations may be needed.try running setting the multiplier MULT on the EQSLV command to greater than 1.0 but less than 3.0" Can anyone guide me with this ?
