Applying Transient Velocity at the inlet BC -- CFD Online Discussion Forums

August 13, 2016, 01:25	Applying Transient Velocity at the inlet BC	#1
OpenFOAM-2016 New Member Mike Join Date: Jul 2016 Posts: 6 Rep Power: 9	Hi all I did some search on internet but couldn't find my answer. I wanna apply a transient velocity profile at the inlet. I mean the velocity at the inlet is not fixed and changes with time. Let's say for example sinusoidal. How can I set such velocity profile? do I need to write a UDF? I've never written a UDF before? Don't know what to do. Thank you.
