Creates a mapper for general fmesher function space objects.
Usage
bru_mapper_fmesher(mesh)
# S3 method for class 'bru_mapper_fmesher'
ibm_n(mapper, ...)
# S3 method for class 'bru_mapper_fmesher'
ibm_values(mapper, ...)
# S3 method for class 'bru_mapper_fmesher'
ibm_jacobian(mapper, input, ...)Arguments
- mesh
An
fmesherobject to map, supported by fmesher::fm_basis(mesh, input)and fmesher::fm_dof(mesh).- mapper
A mapper S3 object, inheriting from
bru_mapper.- ...
Arguments passed on to other methods
- input
Data input for the mapper.
Details
For fmesher before version "0.2.0.9002", fmesher::fm_mesh_1d
objects will be handed over to bru_mapper.fm_mesh_1d(), which handles NA
inputs for older fmesher versions.
