Description

Currently we just have an allocating version for evaluate_at_points and the internal function evaluate_at_points! which requires knowledge about the internals to use. We should widen the user-facing portion by adding the following functions

  • evaluate_at_points!(values::AbstractVector, ph::PointEvalHandler, proj::L2Projector, dof_vals::AbstractVector)
  • evaluate_at_points!(values::AbstractVector, ph::PointEvalHandler, dh::DofHandler, dof_vals::AbstractVector)
  • evaluate_at_points!(values::AbstractVector, ph::PointEvalHandler,dh::DofHandler, dof_vals::AbstractVector, fname::Symbol)

Furthermore we might want to restrict the evaluation to subdomains, which requires a little bit of refactoring for the internals.

Contributor guide

Research direction
Implement the non allocating evaluate at points! functions as described. Consider refactoring internals to support subdomain restriction.
