abadiee New Member Amir Join Date: Jul 2010 Location: The UK Posts: 2 Rep Power: 0	I am simulating microchannels in FLUENT. I have a single channels with rectangular crosssection. Hydrolic diameter is 0.0015, Length is 1 cm. BC: Inlet> Velocity inlet Outlet> Outflow Bottom wall > Heat flux: 100000 w/m2, Th:0.0005m Upper and side walls: Adiabatic, Th:0.0005m But What I get in pressure contour is negative pressure inside the channel which does not make any sense. Can I have your opinions on the issue please.
