Hi everyone,<\/p>\n

I read the post answered by @DrAmine<\/a> and @Kremella<\/a> (\/forum\/discussion\/2878\/journal-file-for-dynamic-mesh-update<\/a>) and think it will save me a lot of time if I could also run my multi-stage transient model with a journal file.?<\/span> I have defined the boundary conditions, dynamic motion\/zones, cell registers etc on the GUI and now all I need is to write a jounral file that can automatically run for multiple stages. However, the TUI command lines does not work very well?<\/span>. Any help will be very much appreaciated.<\/p>\n

Command line:<\/strong><\/p>\n

\/file> start-journal<\/p>\n

Journal file name[] aaa.jou<\/p>\n

Opening input journal to file "aaa.jou"<\/p>\n

\/solve\/initialize\/intialize-flow<\/p>\n

\/solve\/patch<\/p>\n

Domain> nozzle_internal<\/p>\n

invalid command [nozzle_internal]<\/p>\n

()<\/p>\n

cell zone id\/name(1) [()] nozzle_internal<\/p>\n

<\/p>\n<\/p>\n

Error: eval: unbound variable<\/p>\n

Error Object: nozzle_internal<\/p>\n

Simulation Steps:<\/strong><\/p>\n

1. Start journal file<\/p>\n

2. Initialize the case<\/p>\n

3. Patch cell register "nozzle_internal" fluid mixture to pressure 10000Pa<\/p>\n

4. Patch cell register "nozzle_internal" fluid water to volume fraction to 1<\/p>\n

5. Setup number of time steps and the step size for stage 1<\/p>\n

6. Run the model<\/p>\n

7. Delete the cell register "nozzle_internal"<\/p>\n

8.Modify the number of time steps and the step size for stage 2<\/p>\n

9.set up and Repeat 8 for other stages<\/p>\n

Questions:<\/strong><\/p>\n

1. How to patch for a cell register when the TUI console does not regonise the name of it and it does not have an ID (The command lines above shows the error)<\/p>\n

2. How to differentiate mixture and pure fluid(water) in TUI and what are the commands for defining pressure and volume fraction (The TUI command text guide under patch does not have an explanation)<\/p>\n

3. How to setup the number of time steps and the step size, and run (the TUI command line guide only introduced solve\/iterate but not very useful for transient, I have tried solve\/set\/adaptive-time-stepping but the system cannot recognise this command)<\/p>\n

4.What are the commands in the brackets<\/p>\n
