inla.fmesher.smorg {INLA}R Documentation

Compute various mesh related quantities.

Description

[Deprecated] since ⁠23.08.18⁠. Use the methods in the fmesher package instead; see details below.

Low level function for computing finite element matrices, spherical harmonics, B-splines, and point mappings with barycentric triangle coordinates.

Usage

inla.fmesher.smorg(
  loc,
  tv,
  fem = NULL,
  aniso = NULL,
  gradients = FALSE,
  sph0 = deprecated(),
  sph = deprecated(),
  bspline = NULL,
  points2mesh = NULL,
  splitlines = NULL,
  output = NULL,
  keep = FALSE
)

Arguments

loc

3-column triangle vertex coordinate matrix.

tv

3-column triangle vertex index matrix.

fem

[Deprecated] Use fmesher::fm_fem() instead. Maximum finite element matrix order to be computed.

aniso

[Deprecated] Use fmesher::fm_fem() instead. A two-element list with \gamma and v for an anisotropic operator \nabla\cdot H \nabla, where H=\gamma I + v v^\top

gradients

[Deprecated] Use fmesher::fm_fem() instead. When TRUE, calculate derivative operator matrices dx, dy, and dz.

sph0

[Deprecated] Use fmesher::fm_raw_basis() instead.

sph

[Deprecated] Use fmesher::fm_raw_basis() instead.

bspline

[Deprecated] Use fmesher::fm_raw_basis() instead. Rotationally invariant B-splines on a sphere. 3-vector with number of basis functions n, basis degree degree, and a logical; TRUE uniform knot angles, FALSE for uniform spacing in \sin(latitude).

points2mesh

[Deprecated] Use fmesher::fm_bary() instead. 3-column matrix with points to be located in the mesh.

splitlines

[Deprecated] Use fmesher::fm_split_lines() or fmesher::fmesher_split_lines() instead. A list with elements loc (3-column coordinate matrix) and idx (2-column index matrix) describing line segments that are to be split into sub-segments at triangle boundaries.

output

Names of objects to be included in the output, if different from defaults.

keep

When TRUE, for debugging purposes keep the fmesher I/O files on disk.

Value

A list of generated named quantities.
