OK… I may have found my own answer. It, as it usually is, may be PICNIC (problem in chair, not in computer). I found the “surface integration” check box within line integration (I assume that means completing the revolve). Now the answer seems to work out. Below are the new answers using extremely fine as the initial solution. I feel a bit silly, but I had assumed that the Axisymmetric model did the revolve when you took the line integral across the boundary.

Extremely Fine:
240 0.1000000 0.00099 240 240 240 2.7e-011 9.1e-014
Stationary Solver 1 in Solver 2: Solution time: 43360 s (12 hours, 2 minutes, 40 seconds)
Physical memory: 14.34 GB
Virtual memory: 18.97 GB
w2*hmnf.rho (kg/s) w2*hmnf.rho (kg/s)
8.26522e-5 8.27247e-5

Normal:
51 0.8000000 0.00099 51 51 51 81 0.00051 9.9e-007
Stationary Solver 1 in Solver 3: Solution time: 566 s (9 minutes, 26 seconds)
Physical memory: 2.23 GB
Virtual memory: 3.01 GB
w2*hmnf.rho (kg/s) w2*hmnf.rho (kg/s)
7.97197e-5 8.00929e-5

My next question is: how do I evaluate multiple cut lines so that I can see the mass flow as function of position along the pipe? I can create a data set of cut lines along the pipe, but I don’t know how to evaluate the integrals at each of them. When I try, it wants to evaluate as if the data set is one long line, not several individual lines.
