cellFaces
Description
Examples
Find faces belonging to two cuboids in a geometry consisting of four stacked cuboids.
Create a geometry that consists of four stacked cuboids.
gm = multicuboid(5,10,[1 2 3 4],"ZOffset",[0 1 3 6])gm =
DiscreteGeometry with properties:
NumCells: 4
NumFaces: 21
NumEdges: 36
NumVertices: 20
Vertices: [20×3 double]
Plot the geometry with the cell labels.
pdegplot(gm,"CellLabels","on","FaceAlpha",0.2)
Find faces belonging to cells 1 and 3.
faceIDs = cellFaces(gm,[1 3])
faceIDs = 1×12
1 2 3 4 5 6 7 12 13 14 15 16
Plot the geometry with the face labels.
pdegplot(gm,"FaceLabels","on","FaceAlpha",0.2)
Find faces belonging to the outer cuboid in a geometry consisting of two nested cuboids.
Create a geometry that consists of two nested cuboids of the same height.
gm = multicuboid([2 5],[4 10],3)
gm =
DiscreteGeometry with properties:
NumCells: 2
NumFaces: 12
NumEdges: 24
NumVertices: 16
Vertices: [16×3 double]
Plot the geometry with the cell labels.
pdegplot(gm,"CellLabels","on","FaceAlpha",0.2)
Find all faces belonging to the outer cell.
faceIDs = cellFaces(gm,2)
faceIDs = 1×10
3 4 5 6 7 8 9 10 11 12
Find only the internal faces belonging to the outer cell. Internal faces are faces shared between multiple cells.
faceIDs_int = cellFaces(gm,2,"internal")faceIDs_int = 1×4
3 4 5 6
Find only the external faces belonging to the outer cell.
faceIDs_ext = cellFaces(gm,2,"external")faceIDs_ext = 1×6
7 8 9 10 11 12
Plot the geometry with the face labels.
pdegplot(gm,"FaceLabels","on","FaceAlpha",0.2)
