Creates a mapper for general fmesher function space objects.
Usage
bm_fmesher(mesh)
bru_mapper_fmesher(...)
# S3 method for class 'bm_fmesher'
ibm_n(mapper, ...)
# S3 method for class 'bm_fmesher'
ibm_values(mapper, ...)
# S3 method for class 'bm_fmesher'
ibm_jacobian(mapper, input, ...)Arguments
- mesh
An
fmesherobject to map, supported by fmesher::fm_basis(mesh, input)and fmesher::fm_dof(mesh).- ...
Arguments passed on to other methods
- mapper
A mapper S3 object, inheriting from
bru_mapper.- input
Data input for the mapper.
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.
