I want to simulate a deforming pipe and the alteration of the air flux in that pipe because of the deformation, and I have been able to do it.

But after I increased the deformation of the pipe, this error came after the simulation concluded.

Hear the Error (sorry for the Language doing the simulation in Germany):

Translating: The Execution of the Coupling was completed successfully.

After it completes, the Fatal error appears, and then it starts to try to exit but never completes; it needs to be forcefully terminated in order to try again.

Has anyone any Idea what this error means or how to avoid it?

Hello, 

I suggest going over the log files for each participant to get a more information about what caused this failure. For example, do you get Negative Volume cells in Fluent, etc.

Hi

I checked, and in both Fluid and Mechanical the Error was: “Hard exit for cases where the mesh flag is empty usually for debug NLAD runs.”

or something similar,

I don't expect Fluent and Mechanical to have the same outputs.

Please check the latest .trn file for Fluent and .out file for Mechanical for any warnings or error messages.

sorry for the delay

thanks for the help i checked the files and in fluent was error negetav cell volume, i did the simulation again and strangely never had the error again.
