Mapper for general fmesher function space objects

Source: R/mappers.R
bm_fmesher.Rd

Creates a mapper for general fmesher function space objects.

Usage

bm_fmesher(mesh)

bru_mapper_fmesher(...)

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

Arguments

mesh

An fmesher object to map, supported by fmesher::fm_basis(mesh, input) and fmesher::fm_dof(mesh).

...

Arguments passed on to bm_fmesher()

Value

A bm_fmesher object.

Details

Handles indexed mapping for all fmesher classes that support fm_dof() and fm_basis() methods. For non-indexed mapping of fm_mesh_1d objects, use bru_mapper(mesh, indexed = FALSE) which invokes the bru_mapper.fm_mesh_1d() method.

Functions

  • bru_mapper(fm_mesh_2d): Equivalent to calling bm_fmesher(). Note: Prior to version 2.12.0.9021, this returned a bru_mapper_fm_mesh_2d object. Also see the note for bru_mapper.fm_mesh_1d().
