Hi,
In order to make sure I'm running OpenFoam correctly, I am running simpleFoam for a straight pipe with a small pressure differential that should induce a constant velocity through the pipe. I use pressureInlet and pressureOutlet to specify the pressures on either end of the pipe and initialize the internal flow to the velocity I expect from Bernoulli. What I keep seeing is that the velocity is constant through the pipe, but the magnitude just keeps rising with each iteration, and never converges. I can run this case in Fluent, and it converges very quickly. Does anyone have any idea why the velocity field would increase in this way? Greg Z. |
