I would like to simulate flowing over cylinder. I have exported file with .msh extention.



My .geo script is as below;

Point(1) = {0, 0, 0, 1.0};
Point(2) = {0.707106781, 0.707106781, 0, 1.0};

Point(5) = {2, 2, 0, 1.0};

And i got output as below;

Thank you in advance for your helping

Hello,

Not an openfoam user but two things that comes to my mind looking at your geo file:
- z=cte planes are not affected any Physical Surface (slip wall ? symmetry ?)
- No Physical Volume is present in geo file, then I suspect gmsh does not write any 3D element
