Field Function for Rotation around a COS wanted

TRGH · March 19, 2016, 10:56

Hi, I am currently searching for a field function which allows me to rotate an overset mesh around a cartesian COS 2 seconds after starting the simulation and stopping after 0.05s. Can anybody here help me or do you have a guide how to set up field functions?

Thank you in advance,
TRGH

I figured it out, if somebody needs it:

($Time<=2)?0:
(
($Time>2&&$Time<=2.03)?1:
(
($Time>2.03&&$Time<=4)?0:
(
($Time>4&&$Time<=4.03)?1:
($Time>4.03)?0:0
)
)
)

Replace the 1 with your desired speed and add "Rotation" (or Translation) under Tools-Motions, set your rotation rate (or Translation velocity) as [TheNameofYourFieldFunction].
