Hi all,

I earlier had done a simple pipe simulation and observed that the radial velocity distribution is parabolic, and in accordance with the known analytical expression. However, when I see the result today on Windows (by first creating an empty .foam file), the velocity at the walls is not zero. I took the data back to linux, where I earlier performed the simulation and visualized the results, and opened using the paraFoam command (that simply creates a .OpenFOAM file). Here, the results are as expected. When I manually created an empty .foam file and load this to paraview in linux, the results are again bad. Please see the attached two images to see what I mean.

Is there a way to circumvent this problem? How do you guys generally visualize results in Windows? I am using version 5.4.0 on windows.

Thanks in advance,
Ajay

The OpenFOAM reader in paraview loads the patches automatically, whereas the builtin .foam reader does not.
I think, that paraview tries to extrapolate the data to the boundary and gets a wrong result. When you load the patches together with internal mesh it should be working.

When you want to check if your data or paraview is wrong just look into the result files.
