Reply To: How to recover the last saved state in system coupling when it is crashed

[Rahul Mule]

Hello Tayyaba,

Good to know that the files are recovered.

Keep backup of files and clear the generated data from system coupling solution cell. Try running it again.
If that doesn't help. Remove the connections of coupling participant from system coupling and make them again.

Please refer following tutorial for running FSI case in workbench:

Hope this helps.
