Compute connected mesh subsets
Description
![[Deprecated]](../help/figures/lifecycle-deprecated.svg)
Compute subsets of vertices and triangles
in an inla.mesh object that are
connected by edges. This function is deprecated from INLA 25.4.10 when
fmesher version 0.3.0.9005 or later is installed, which has
fm_mesh_components().
Usage
inla.mesh.components(mesh)
Arguments
mesh |
An |
Value
A list with elements vertex and triangle, vectors of
integer labels for which connected component they belong, and info, a
data.frame with columns
component |
Connected component integer label. |
nV |
The number of vertices in the component. |
nT |
The number of triangles in the component. |
area |
The surface area associated with the component. Component labels are not comparable across different meshes, but some ordering stability is guaranteed by initiating each component from the lowest numbered triangle whenever a new component is initiated. |

Examples
# Construct two simple meshes:
library(fmesher)
loc <- matrix(c(0, 1, 0, 1), 2, 2)
mesh1 <- fm_mesh_2d(loc = loc, max.edge = 0.1)
bnd <- fm_nonconvex_hull_inla(loc, 0.3)
mesh2 <- fm_mesh_2d(boundary = bnd, max.edge = 0.1)
# Compute connectivity information:
conn1 <- inla.mesh.components(mesh1)
conn2 <- inla.mesh.components(mesh2)
# One component, simply connected mesh
conn1$info
# Two disconnected components
conn2$info
