I run the fluent nohup in the parallel computer, and it lasts for 2 days. Today morning, I went to see the results, it strangely stops and it shows the below error. Why? I want to help. Thanks for advance.

Code:

Excuse, have you solved this problem? Recently I also come across this issue when running parallel FLUENT on Linux Computers. It is as follow:

Flow time = 0.64349997, time step = 12870
7130 more time steps

Updating solution at time levels N and N-1.
done.
iter continuity x-velocity y-velocity z-velocity time/iter

Any other inputs is helpful,
thanks a lots!

Today, I may find the reason, Yes,may.
Do you change the nodes in parallel computer?

The nodes text may:
Code:
node1
node1
node2
node2
It may cause the problem.

But if no change, what I mean like that:
Code:
node1
node1
I get Ok but for only one calculation.
Maybe Time will tell, and you just wait and see
