I hope XP 64Bit?
How do you start your simulation? Can you post the command line here? |

Sure XP 64Bit.
I didn't use the command line, but tried in the program panel (File -> Load Simulation -> Menu parallel). If you know another way, tell me please, I'm new in star ccm+. Thank you |

When you do this way you have shown the comand-line below in the dialog.
What parallel options you select? Do you have enough licenses? |

Yes I have enough licenses.
The option selected are: "controller on a worker host" and then I set the name of the machine in the "parallel hosts", where I have to specifiy number of processes. In the line command: "star ccm+ -server -on NAME HOST : 4" |

I actualy have ccm under linux, but I can look under windows next week.
Under linux I select "Run all processes on local host". The "controller on a worker host" I only have when I select "specify parallel hosts". My comand lin ies starccm+ -server -np X (X=numbers of cpu's) |

maybe you work on a single machine with more than a cpu.
I need to work on more machines. Any suggest? Do you have a user guide? thank you |

Well, the error says it can't connect, so see if you can even ping the machines (start>run>cmd>"ping MACHINE_NAME").
Then, turn of all the firewalls, and try again. Let us know what happens. Also, I assume you know that you can run parallel only with machines with same operating system AND architecture (all have to be 64-bit or 32-bit). |
