ExtendableFEMBase

ExtendableFEMBase.jl provides foundational data structures and tools for assembling custom finite element solvers in Julia. It is designed for flexibility, efficiency, and extensibility, and serves as the low-level backend for ExtendableFEM.jl. All functionality is built on top of ExtendableGrids.jl.

Features

• Wide range of finite element types (H1, Hdiv, Hcurl, etc.)
• Flexible finite element spaces (FESpace)
• Block-structured matrices and vectors (FEMatrix, FEVector)
• Primitive and composite function operators (e.g., gradient, divergence)
• Efficient basis evaluation and quadrature routines
• Interpolation and reconstruction operators
