I have dug into the tutorials and see the same thing happen in interFoam/nozzleFlow2D, for instance. The mesh check also clearly shows that the grid is indeed 2D but for some reason has 3 solution directions: Code: ```Checking geometry... Overall domain bounding box (-0.65 0 -0.028352602) (1.95 0.65 0.028352602) Mesh has 2 geometric (non-empty/wedge) directions (1 1 0) Mesh has 3 solution (non-empty) directions (1 1 1) Wedge side_pos with angle 2.4976236 degrees Wedge side_neg with angle 2.4976236 degrees All edges aligned with or perpendicular to non-empty directions. Boundary openness (8.0639549e-19 -3.9251831e-15 2.7113778e-14) OK. Max cell openness = 2.4730408e-15 OK. Max aspect ratio = 125.01216 OK. Minimum face area = 2.5901831e-11. Maximum face area = 0.0029599635. Face area magnitudes OK. Min volume = 1.6935059e-14. Max volume = 0.00013206161. Total volume = 0.0478444. Cell volumes OK. Mesh non-orthogonality Max: 75.256619 average: 4.8024892 *Number of severely non-orthogonal (> 70 degrees) faces: 1. Non-orthogonality check OK. <
