2way FSI Fluent Mechanical SETUP Problems
 
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 :(

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

ok
this is a license problem, the following thread helped:

All that needs to be done to eliminate this error is to change licensing prefs from "Share a single license between applications when possible" to "use a separate license for each application." To check the settings, in Workbench go: Tools>License Preferences... and the GUI will open.

FSI - Setup Problem
 
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 ?

I am doing a similar setup for FSI but I receive the following error message.


echec de la mise à jour du composant solution dans couplage de système.
System coupling run with errors.
Additionnal information :preconditioned 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

Trigui,
Have a look at the following link, it might apply to your case as well:
