Parametric extension of a FEFunction in Gridap. Subtypes:

• SingleFieldParamFEFunction
• MultiFieldParamFEFunction

end

abstract type SingleFieldParamFESpace{S} <: SingleFieldFESpace end

Parametric extension of a SingleFieldFESpace in Gridap. The FE spaces inhereting are (trial) spaces on which we can easily define a ParamFEFunction.

Subtypes:

• TrivialParamFESpace
• TrialParamFESpace

TrialParamFESpace{S} <: SingleFieldParamFESpace{S}

Trial FE space equipped with parametric dirichlet values

TrivialParamFESpace{S} <: SingleFieldParamFESpace{S}

Wrapper for non-parametric FE spaces that we wish assumed a parametric length

parameterize(a::SparseMatrixAssembler,r::AbstractRealization) -> SparseMatrixAssembler

Returns an assembler that also stores the parametric length of r. This function is to be used to assemble parametric residuals and Jacobians. The assembly routines follow the same pipeline as in Gridap

HomogeneousTrialParamFESpace(U::SingleFieldFESpace,plength::Int) -> TrialParamFESpace

Returns a TrialParamFESpace equipped with homogeneous parametric dirichlet values

TrialParamFESpace!(dir_values::AbstractParamVector,space::SingleFieldFESpace,objects
  ) -> TrialParamFESpace

Allows do-block syntax for the construction of a TrialParamFESpace

get_vector_type2(f::SingleFieldParamFESpace) -> Type

Returns the vector type of the underlying un-parametric FESpace contained in f

param_zero_dirichlet_values(f::FESpace) -> AbstractParamVector

Parametric version of the function zero_dirichlet_values in Gridap

param_zero_free_values(f::FESpace) -> AbstractParamVector

Parametric version of the function zero_free_values in Gridap
