Overview

A lightweight 2D FEM solver for elliptic PDEs.

Basic Features:

• Pure Python implementation using NumPy and SciPy.
• Provides a simple interface for reading Gmsh meshes.
• Supports both conforming and nonconforming triangular meshes.

Additional Details:

• Implements the control-volume finite-element method (CVFEM) with linear (P1) elements.
• Implements the Galerkin finite-element method (FEM) with linear (P1) elements.
• Provides a simple framework for generating nonconforming triangular meshes.
• Supports mesh refinement and coarsening.
• Supports conservative interpolation during mesh refinement/coarsening.
• Supports construction of discrete Dirichlet-to-Neumann operators.
