sine wave field function???
I'm trying to write a field function such that the wall of my pipe will expand and contract in a sinusoidal waveform over a period of 3 seconds in STAR CCM+ v7.
I am using a morphing motion. This is what i have got so far:
[0.00009+0.00003*sin(2*3.14*$Time), 0, 0]
he wall is moving but i cannot get it to work correctly or link it to the time i have specified.
I'm new to writing field functions and I am finding it very difficult, any information on any aspect of this topic at all would be hugely appreciated.
Thanks a million
