Hi all, 

I am trying to run System Coupling ( with Fluent and Transient Structural). When, it is running, after some time whenever some error occurs, I cannot retrieve the solution upto that point. For example, when I am running simulation for 5 seconds and the error occurred after 4 seconds of simulation, shouldn't I be able to recover the solutions to that point? It is unusual because I can do that in Fluent alone or Structural transient alone but when I run with system coupling, it seems like I cannot do that in System Coupling. If anybody has any idea on how to retrieve those solutions, it would be a big help.

Thanks,
Bibek

Hi Bibek,

There are two purposes for writing intermediate solution files:

 

1) Produce files which can be post-processesed to extract information on the simulation

2) Produce files allowing for a restart/continuation of the simulation

 

For (1) the approach is no different than a Fluent-only or Mechanical-only simulation. In Fluent and Mechanical set each solver to write the desired data.

For (2) this is controlled in System Coupling under Execution Control > Intermediate Restart Data Output.

 

Regards,

Ryan
