Hi everybody,

I have made the setup of a Gasturbine simulation. Now i'd like to simulate that at different massflows and révolutions. Is there a way i can create the different def files by batch mode? It would just be necessary to change massflow and révolutions.

Any ideas?

Check for the command line arguments (e.g. -ccl) of the cfx5solve. You can create "new" def files from an existing one and run them OR run the same def-file with the -ccl and input snippets changing the app. places each time.

You can add a ccl to modify the original def-file during start up. Just add a -ccl name.ccl to your start-up command. Open in Pre a Domain with the Command editor to see how the ccl should look like.
For instance to change the massflow it is sth like (untested!):

FLOW: Flow Analysis 1
&replace BOUNDARY: Inflow
Boundary Type = INLET
Location = inlet
Mass Flow Rate = newMassFlow
Option = Bulk Mass Flow Rate

Edit: too slow....
