I am doing a 5000 iteration simulation in Ansys Fluent.


I have started my computations with Under relaxation factors for Mom=0.1, kinetic energy =0.3, omega =0.3.



I would like to increase my URF by 0.1 after every 500 iterations, till I reach completion.


How to do it using Execute Command of Ansys Fluent

Create text file in your working directory, put following code inside.
It would be JOURNAL, so it should have .jou, however .txt still works well

solve set under-relaxation mom 0.1
solve set under-relaxation k 0.3
solve set under-relaxation omega 0.3
solve set iterate 500
solve set under-relaxation mom 0.2
solve set under-relaxation k 0.4
solve set under-relaxation omega 0.4
solve set iterate 500
solve set under-relaxation mom 0.3
solve set under-relaxation k 0.5
solve set under-relaxation omega 0.5
solve set iterate 500
....

Make all needed setting, initialize your case. Then run journal:
File -> Read -> Journal... -> your file
