controling rotational velocity of rotating inner mesh

Hello,
Given a rotating meshed disk inside my domain, can I use user_scripts to control the speed of rotation based on what is happening inside my simulation?
thanks
Susan

Hello Susan,
Just to confirm that I've understood your question, you want to control the rotational speed of the disc using, for example, some form of a fluid force i.e. pressure difference or viscous forces acting on the disc, without having to specify a rotational speed.

Yes that is it exactly. Sorry I was not more clear!

Hi
You can not do that with cs_user_scripts. Are you using rotor/stator module ?

Hi Jacques,
I was planning to yes. But I was hoping there was some way to control the rotational speed based on what is happening during the simulation and not just by giving a fixed value in usini
thanks

Hello,
You can do that, but not in user_scripts.py, whic is for the run script. An appropriate user subroutine might be "cs_user_extra_operations", but check the descriptions of the different user subroutines in examples and the documentation to check what is the best fit.
