After setting up computational analysis of specific test section, with specific flow velocity for both cases, it starts iteration and starts creating results, and stops once calculations, or number of time steps are finished. Thus again, I have to setup, with different values, which I have to change myself, the computational analysis, to run the model for further iterations, this results in time gap between two sessions of fluent, and software stays ideal, between that time, which I can't afford to loose that time. This also takes the total 7 hours of simulation and prolong it to 3 days.
Now I know that, there is a section, in which one can give commands to fluent, to modify the case, by itself, save the previous case and data, and take new values form document(I guess UDF file), for further calculations, and start the flow analysis until, it finished with its number of Iterations, or user say so. Can anyone help me in this issue, and if anyone knows how to setup, can you tell me the procedure? |

You need to familiarize yourself with the TUI commands (the text command user input that drives Fluent) and not the GUI commands. No UDF is needed.
Make a journal file of such commands to modify the boundary conditions as needed. And read the journal file after you have launched fluent. For example rcd "casename" modify boundary-conditions blah blah blah blah wcd "name" yes solve iterate 10000 wcd "name" yes modify boundary-conditions blah blah blah blah wcd "name" yes solve iterate 10000 wcd "name" yes modify boundary-conditions blah blah blah blah wcd "name" yes solve iterate 10000 wcd "name" yes modify boundary-conditions blah blah blah blah wcd "name" yes solve iterate 10000 wcd "name" yes modify boundary-conditions blah blah blah blah wcd "name" yes solve iterate 10000 wcd "name" yes exit |
