Hello,

I've got a strange error in Fluent; I haven't found the solution on the internet.

After some time when the Fluent is opened and I'm not using it, I get a message in TUI:



999999: mpt_connect: error: connect failed: No error

999999: mpt_connect: error: connect failed: No error

999999: mpt_connect: error: connect failed: No error

2: mpt_establish_connection: error: unable to connect: No error
3: mpt_connect: error: connect failed: No error

3: mpt_connect: error: connect failed: No error

3: mpt_connect: error: connect failed: No error

3: mpt_establish_connection: error: unable to connect: No error

MPI Application rank 0 exited before MPI_Finalize() with status -1


and I can't see the mesh - only white background.

Have you got any idea, how to fix it?

Regards!

Just kill Fluent and start over again.
This is one of the events where Fluent screws your work. The source can be anything: numeric, wrong input, divergence.........

Thank you. I did that and It worked.
But I still don't know the source of the problem. Might be anything.

Thanks.

LuckyTran has a spectacular aura aboutLuckyTran has a spectacular aura about
Code:
mpt_connect: error: connect failed: No error
The parallel process tried to send a msg using an existing connection but couldn't.
Code:
mpt_establish_connection: error: unable to connect: No error
The parallel process tried to (re)establish a connection but couldn't.
Code:
MPI Application rank 0 exited before MPI_Finalize() with status -1
This is almost literal. The application exited (or aborted) before it made it to MPI_Finalize. Meaning it ended when it wasn't supposed to, or crashed.

Are you running Fluent on your computer that is using wireless or something? Maybe your network connections go to sleep because of power saving settings or something.

@FSM I didn't solve my problem, but now I don't need to use Fluent on the computer with this issue, so haven't try yet. Maybe try to reinstall ANSYS package, please write then if it helped.

@LuckyTran I'm using wireless connection, but I haven't any problems with this.

I am still not sure about the reason of that error, but I guess that was because of the connection with the license server, which is made by internet in my case. I am not using a wireless connection but it is likely that I had some internet problem and a cut in communication with the license.
In my case, I just killed Fluent and started again from the point it stopped. It worked.
I am not sure if reinstall the Ansys package would work. Maybe it is one possible solution, in case of just killing fluent and starting again didn't work.

I have license and calculation on one machine. So there is no communication problem.
It just happens when there is a miscommunication between the cores. Because (in my opinion) the mpi error implies something went wrong in the parallelisation, which is where mpi comes into play.
So I think something went wrong on one of the cores. Either through a fpe, wrong setting, divergence, or what so ever. It can be anything. Then one processor stops and is no longer communicating with the others or the master.
