fm_sizes

Compute effective sizes of faces/cells and vertices in a mesh

Usage

fm_sizes(...)

# S3 method for class 'fm_mesh_2d'
fm_sizes(mesh, ...)

# S3 method for class 'fm_mesh_3d'
fm_sizes(mesh, ...)

Arguments

...

Passed on to submethods

mesh

object of a supported mesh class

Value

A list with elements of simplex size information. For 2D meshes:

face

Vector with the area of each triangle

vertex

Vector with the triangle area apportioned to each vertex

face_edge

A matrix with one row per triangle and 3 columns, with edge lengths for the edge opposing each triangle vertex.

For 3D meshes:

cell

Vector with the volume of each tetrahedron

vertex

Vector with the tetrahedron volume apportioned to each vertex

cell_face

A matrix with one row per cell and 4 columns, with triangle areas for the triangle opposing each tetrahedron vertex.

cell_edge

A matrix with one row per cell and 4 columns, with edge lengths for the edge anchored at each vertex, pointing to the next vertex in the internal ordering.
