Hi foamers. I am simulating a fan case. The mesh is generated by autogrid5 and the mesh file is .msh type. While the mesh is only one passage of the fan, I use the createPatch to make the periodic face cyclic. The createPatchDict is shown below.
name cyclic-0 Patchinfo type cyclic Neighbor patch cyclic-1 Transformation type: rotational Rotation axis: (0 0 1) Rotation center: (0 0 0) Construct from patches Patch (periodic1) name cyclic-1 Patchinfo type cyclic Neighbor patch cyclic-0 Transformation type: rotational Rotation axis: (0 0 1) Rotation center: (0 0 0) Construct from patches Patch (periodic2) I am sure that the periodic patches is matching. But when I used the createPatch utility, I was warned that "face area does not match neighbour by xx% --possible face ordering problem. " Has someone met this problem? Thanks for anyone's help. |
