ExPDE

Expression Templates for Partial Differential Equations

Overview

An interesting collection of efficient, user-friendly and flexible C++-libraries for the problem-specific solution of partial differential equations, as well as powerful implementation policies for applying the Expression Templates technique!

• EasyExtemps – Simple manners for implementing Expression Templates
• ExPDE library – C++-library for solving PDEs with very math-like interface
• Unstructured block grids
• Staggered grids
• Colsamm – Efficient computation of local discretization matrices

Main developer: Prof. Dr. Christoph Pflaum  (Professorship for Numerical Simulation using Highest-Performance Computers)
