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? Thanks Last edited by Daniel Frederik; June 18, 2014 at 07:25. |

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 DOMAIN: SVWG &replace BOUNDARY: Inflow Boundary Type = INLET Location = inlet MASS AND MOMENTUM: Mass Flow Rate = newMassFlow Option = Bulk Mass Flow Rate END END END END Edit: too slow.... |
