Simulation running in background
 
Dear All,

I am running a simulation in background (using foamJob). It started well and after some hours, I had a problem: the simulation seems to run properly, but nothing is written.

In fact, if I give the `top' command, I get this:
Code:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND           
11571 rduser    20  0  383m  94m 4368 R  100  2.4  2434:38 buoyantPimpleFo

Also, trying to give the `ps -ef | grep rduser' command, I get the following output:
Code:

rduser@slnxepmi05:/OPENFOAM/cases/moving_door_def_flow/test/opening/we3Ter$ ps -ef | grep rduser

rduser@slnxepmi05:/OPENFOAM/cases/moving_door_def_flow/test/opening/we3Ter$

The problem is that nothing is written after a certain time step and this happens for 2 different simulation (the 2 that are running as you can see in the commands above).

Any idea? What could I do?

Thanks a lot,

Samuele

how are your output setting in system/controlDict defined?
