Hello,
I am looking for a solution how to split a given STL-file into separate patches along feature lines. The STL-file defines the domain to be meshed, which is a volume with curved boundaries and a few "sharp" edges (feature angle <150°) that are correctly handled by snappyHexMesh after running surfaceFeatureExtract.

I need these individual patches to perform extrudeMesh, for example, with different settings for each patch.

Is it possible to use output from either surfaceFeatureExtract or snappyHexMesh or from other tools to get information such as
- the boundaryMesh consists of n separate patches
- patch number 1 contains faces f1,f2,f3...
- patch number 2 containes faces f101,f102,f103...
- patch number n contains faces f901,f902,...?


Thanks
Felix

Dear Felix, did you find an answer to your question?

Dear all,

I have a similar issue, where I have a cylinder mesh in snappyHexMesh and it is all part of a single patch.

(that cylinder could come from a stl file or from a searchableCylinder)

Now, what would be the easiest way to split the surface along the sharp edges in order to get a TOP patch, a SIDE patch and a BOTTOM patch?

Many thanks
