Default Fluent: change of RMP (of a fan) by time possible?
Posts: n/a

is there any option to chagne the RPM (of fan/turbine) by time? for example: When I chose the "rotating reference frame" in the boundaries for a volume, I can define the RPM, but just constant. Is there a possibility to make the RPM change by time, f.e. 20 seconds +500rpm then the fan should be simulated in the opposite direction of -500 rpm. So 20 sec. + 500, next 20 sec. -500 and so on. Do I have to stop every simulated 20 sec. and change it manualy or can I automate this process?
