Hello,

I have a problem which might be easily fixed with your help. I have created a 3d mesh for an airfoil, which is basically 2d with translation by .2m along z-axis, i.e. it has two identical x-y meshes one at z=0 and another at z=.2 that are periodically linked along z-direction (see figure). I have set boundary types as necessary in Gambit with no errors, but when I check the mesh in fluent I get the following message:

Periodic zone 3: x-translation: min (m) = -1.112668e+000, max (m) = 1.200599e+000
y-translation: min (m) = -1.276517e+000, max (m) = 1.132584e+000
z-translation: min (m) = 2.000000e-001, max (m) = 2.000000e-001
Done.

WARNING: Mesh check failed.

So there appear some strange translations in x and y-directions, which should be zero. When I ignore this warning and start solution in fluent I get meaningless result.

I will be grateful if someone could help me. I feel that it is something elementary.
