January 16, 2013, 16:20	Boundary conditions	#1
mahdi1 Member mahdi Join Date: Jan 2013 Posts: 43 Rep Power: 13	Hello I want to simulate a channel with vegetation by flow-3D code. As far as the length of channel is high and thickness of rigid elements is very small, I want to run the software for a part of channel (for example 2 m) with uniform conditions. my problem is in specifying boundary condition. If I choose periodic boundary for inlet and outlet, How and where can I insert flow depth, velocity or discharge for this part of channel in the software exactly. I would be thankful, if anybody can help me.
