I run my simulation in parallel, it can run smoothly, but every time interval it writes the data, there always some error happens in a proceer or two, sometimes the error is about U, and sometimes it is about vorticity. The error will not happen when I run it in serial. Do you have the approach to deal with that. Thank you very much.

First run:
[140]
[140]
[140] --> FOAM FATAL IO ERROR:
[140] error in IOstream "/work/warling/inlet/3DWindTunnel/processor140/0.03/vorticity" for operation Foam::Ostream &Foam:perator<<(Foam::Ostream &, double)

I have got the answer by myself, it is due to the memory limitation of the cluster. Hope it will be helpful.
