Gridap.FESpacesModule

The exported names are

source
Gridap.FESpaces.CellConformityType

Minimum data required to describe dof ownership. At this moment, the cell-wise ownership is compressed on cell types. This can be relaxed in the future, to have an arbitrary cell-wise dof ownership.

source
Gridap.FESpaces.CellFEType

Minimum data required to build a conforming FE space. At this moment, the some cell-wise info is compressed on cell types. This can be relaxed in the future, and have an arbitrary cell-wise data.

source
Gridap.FESpaces.FEFunctionMethod
FEFunction(
  fs::SingleFieldFESpace, free_values::AbstractVector, dirichlet_values::AbstractVector)

The resulting FEFunction will be in the space if and only if dirichlet_values are the ones provided by get_dirichlet_dof_values(fs)

source
Gridap.FESpaces.FEOperatorType
abstract type FEOperator <: GridapType

A FEOperator contains finite element problem, that is assembled as far as possible and ready to be solved. See also FETerm

source
Gridap.FESpaces.NodeToDofGlueType
struct NodeToDofGlue{T}
  free_dof_to_node::Vector{Int32}
  free_dof_to_comp::Vector{Int16}
  dirichlet_dof_to_node::Vector{Int32}
  dirichlet_dof_to_comp::Vector{Int16}
  node_and_comp_to_dof::Vector{T}
end

Gridap.Algebra.solve!Method
uh, cache = solve!(uh,solver,op,cache)

This function changes the state of the input and can render it in a corrupted state. It is recommended to rewrite the input uh with the output as illustrated to prevent any issue. If cache===nothing, then it creates a new cache object.

source
Gridap.Algebra.solve!Method
uh, cache = solve!(uh,solver,op)

This function changes the state of the input and can render it in a corrupted state. It is recommended to rewrite the input uh with the output as illustrated to prevent any issue.

source
Gridap.FESpaces.compute_conforming_cell_dofsFunction

The result is the tuple

(cell_dofs, nfree, ndiri, dirichlet_dof_tag, dirichlet_cells)

If dirichlet_components is given, then get_dof_to_comp has to be defined for the reference elements in reffes.

source
Gridap.FESpaces.get_algebraic_operatorMethod
get_algebraic_operator(feop)

Return an "algebraic view" of an operator. Algebraic means, that the resulting operator acts on plain arrays, instead of FEFunctions. This can be useful for solving with external tools like NLsolve.jl. See also FEOperator.

source
Gridap.FESpaces.interpolateMethod

The resulting FE function is in the space (in particular it fulfills Dirichlet BCs even in the case that the given cell field does not fulfill them)
