Splits each mesh triangle into (n + 1)^2 subtriangles. The current version drops any edge constraint information from the mesh.

Usage

`n`	number of added points along each edge. Default is 1.

Value

A refined fm_mesh_2d object

Examples

mesh <- fm_rcdt_2d_inla(
  loc = rbind(c(0, 0), c(1, 0), c(0, 1)),
  tv = rbind(c(1, 2, 3))
)
mesh_sub <- fm_subdivide(mesh, 3)
mesh
mesh_sub

plot(mesh_sub, edge.color = 2)

plot(fm_subdivide(fmexample$mesh, 3), edge.color = 2)
plot(fmexample$mesh, add = TRUE, edge.color = 1)
