Gridap.MultiField

The exported names are

• BlockMultiFieldStyle
• ConsecutiveMultiFieldStyle
• MultiFieldCellField
• MultiFieldFEFunction
• MultiFieldFESpace
• MultiFieldStyle
• compute_field_offsets
• interpolate
• interpolate_dirichlet
• interpolate_everywhere
• num_fields
• restrict_to_field

Similar to ConsecutiveMultiFieldStyle, but we keep the original DoF ids of the individual spaces for better block assembly (see BlockSparseMatrixAssembler). Takes three parameters:

• NB: Number of assembly blocks
• SB: Size of each assembly block, as a Tuple.
• P : Permutation of the variables of the multifield space when assembling, as a Tuple.

The DoF ids of the collective space are the concatenation of the DoF ids of the individual spaces.

struct MultiFieldFEFunction <: CellField
  # private fields
end

struct MultiFieldFESpace{S<:MultiFieldStyle,B} <: FESpace
  spaces::Vector{<:SingleFieldFESpace}
  multi_field_style::S
  constraint_style::Val{B}
end

MultiFieldFESpace(spaces::Vector{<:SingleFieldFESpace})

Not implemented yet.

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

like interpolate, but also compute new degrees of freedom for the dirichlet component. The resulting MultiFieldFEFunction does not necessary belongs to the underlying space

num_fields(m::MultiFieldFEFunction)

num_fields(f::MultiFieldFESpace)
