I give the simple case of flow around a cylinder with 3D.

And I have the dat and cas.

First, I save the "crosscylinder.txt" as

rc 3dcross.cas 
rd 3dcross.dat
solve/set/ri 1
file/auto/data 100
solve/set/time-step 1.0e-3
solve/dual 3000 30
exit
yes

and then I save the "nodes.txt" as

node1
node1
node1
node1
node1
node2
node2
node2
node2
node2
node3
node3
node3
node3
node3
node4

node6

node6
node7
node7
node7
node7
node7
node8
node8
node8
node8
node8
node9
node9
node9
node9
node9

And finally I enter the command:

nohup fluent 3d -g -t40 -cnf=nodes.txt <crosscylinder.txt >& run_out.txt &

Then it runs, I close the ssh but after a while, I reopen it and find strange it has done. I open the run_out.txt

it shows

No data created and errors with "Emergency: received SIGHUP signal"

PS1: I use the "LES" and "simplec with standard pressure"

PS2: I have seen the http://www.cfd-online.com/Forums/fluent/40133-error-while-running-parallel.html, but I manually give the nodes like the "nodes.txt" . why it also happens? And I want to ask in this thread but it may upset forum order because it was asked in 2010. So I ask again in my working conditions.

Thanks for looking and need help
