Hi guys,

I generate a cylinder using ICEM, but OpenFOAM says its not closed. How can I modify this? Thanks.
Code:
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Reading surface from "outerCylinder.stl" ...

Triangles    : 8332
Vertices     : 4232
Bounding Box : (-0.238 -0.11424 -0.238) (0.238 1 0.238)

Region	Size

Checking for points less than 1e-6 of bounding box ((0.476 1.11424 0.476) meter) apart.
Found 0 nearby points.

Surface is not closed since not all edges connected to two faces:
    connected to one face : 384
    connected to >2 faces : 0
Conflicting face labels:384
Dumping conflicting face labels to "problemFaces"
Paste this into the input for surfaceSubset

Number of unconnected parts : 3
Splitting surface into parts ...

writing part 0 size 7308 to "outerCylinder_0.obj"
writing part 1 size 384 to "outerCylinder_1.obj"
writing part 2 size 640 to "outerCylinder_2.obj"
I attached my .tin. just export it to .stl. then surfaceCheck.
