Pipe flow

shuo

Hello

I have trying to fo calculation for a laminar pipe flow. I fot results from using FLuent and wanted to compare them with those obtained using icoFoam. The mesh was imported sucessfully and compiled without errors to my knowledge.

Time = 0.5

Mean and max Courant Numbers = 4.1213e+77 1.56978e+79
BICCG: Solving for Ux, Initial residual = 1, Final residual = 30.5736, No Iterations 1001
BICCG: Solving for Uy, Initial residual = 1, Final residual = 37.0907, No Iterations 1001
ICCG: Solving for p, Initial residual = 1, Final residual = 4001.94, No Iterations 5001
time step continuity errors : sum local = 8.45863e+91, global = -3.96813e+87, cumulative = -3.96813e+87
ICCG: Solving for p, Initial residual = 1, Final residual = 0.689595, No Iterations 5001
time step continuity errors : sum local = 5.12229e+99, global = -1.02924e+96, cumulative = -1.02924e+96
ExecutionTime = 1.34 s ClockTime = 2 s

End


I get the time directories: 0 0.1 0.2 0.3 0.4 0.5 constant system VTK

However when i tried to execute foamToVTK to see the results in Paraview I get error messages.
