I am running the gas exchange process of an engine using STAR-CD v3.26. I am able to create the geometry file. When I try to write the problem file, the error message 'error 28 transient data file is not connected' is printed.
what the error message means? |

The error message means your model file is configured for an advanced (i.e. multiple step) transient yet you have no transient file.
You can use the transient module to create the transient file. The transient module is through the pull down menus: Modules->Transient. You can use the command "time,single" to switch back to a simple transient. This method does not require a transient file. |

Thank you again Pauli.
When I make an empty transient file using module->transient, a problem file can be written. In moving mesh case, what is the relation between the transient file and the event file? How do I create a proper transient file in this case? |

In version 3.26, you don't really need the transient module. Enter the command "time, single" & you should no longer need a transient file.
The event & transient files are not related. |
