I was bothered by a simple problem. 2-D tubes with all four sides are walls. The problem is when I try to initialize the pressure field. It display 0 atm no matter how high I give the intial pressure. The setting I looks quite fine and the geometry is very simple. Why this will happen?

Thank in advance

So you have no inlets or outlets, just 4 walls and 2 symmetry planes?

What fluid properties are you using? If it is not compressible, the solver will set the first control volume equal to your domain pressure. This would give you a zero relative pressure everywhere.

Try using a compressible fluid (Air Ideal Gas for instance).

Regards, Robin

Sorry, didn't realize I was looking at the Fluent forum. The same probably applies, however (except for the symmetry planes).
