Flow around a cylinder in chapter 3 of OF Programer's Guide can not run with OF 1.6
 
I am new to OF. This is the error message when I run potentialFoam with OF 1.6.

would some one tell why and how to fix.

Thanks,

There is no error. It has calculated internal values for velocity field U (and flux phi) consistent with your supplied boundary conditions. Check 0/U.

No o/p files generated
 
In the module mentioned above, the start time is 0 and end time is 1. So the o/p directory should show the files for time 0 and 1 (the time-step is 1). But it does not show files for 1. Could somebody help with that?

Thanks

There are no errors above. After that, type foamToVTK and open the /VTK/cylinder.vtk file in Paraview to see the results. I hope this help.
