Hello CFD-user,

for my stationary simulation i want to raise the under-ralaxation factors in the solution controls menu every 300 iterations by 0.2. Is there a way to handle this using for example an udf?
Changing the values manually every time is very annoying, cause there are about 5000 Iterations to calculate.
In the ANSYS Manuals i couldn't find something about it.

Thanks for your answer.

You can control them with console commands -> You can make a journal

Thank you KaLium, now it works great with the following journal file:

solve/set/under-relaxation/pressure 0.1
solve/set/under-relaxation/mom 0.5
solve/set/under-relaxation/k 0.5
solve/set/under-relaxation/e 0.5
solve/iterate 300
solve/set/under-relaxation/pressure 0.12
solve/set/under-relaxation/mom 0.52
solve/set/under-relaxation/k 0.52
solve/set/under-relaxation/e 0.52
solve/iterate 300
...

or shorter:

so set ur pres 0.1 mom 0.5 k 0.5 e 0.5
solve/iterate 300
so set ur pres 0.12 mom 0.52 k 0.52 e 0.52
solve/iterate 300
...

Well done!
