PDELab

General

dune-pdelab is a module based on DUNE with the following aims:

• Rapid prototyping: Substantially reduce time to implement discretizations and solvers for systems of PDEs based on DUNE.
• Simple things should be simple: Suitable for teaching.
• Use of different linear solvers: Exchangeable linear algebra backend.

Its main abstractions are:

• Flexible discrete function spaces:
  • Conforming and non-conforming,
  • hp-refinement,
  • general approach to constraints,
  • Product spaces for systems.
  • Adaptivity and parallel data decomposition.
• Operators based on weighted residual formulation:
  • Linear and nonlinear,
  • stationary and transient,
  • FE and FV schemes requiring at most face-neighbors.

The following applications have been realized using PDELab

• Various elliptic, parabolic and hyperbolic modelproblems.
• Higher-order conforming and discontinuous Galerkin finite element methods.
• Cell-centered finite volume method.
• Mixed finite element method.
• Mimetic finite difference method.
• Incompressible Navier-Stokes equations.
• Two-phase flow.
• Multi-phase flow in porous media.
• Linear acoustics.
• Maxwell's equations.
• DuMu^x is a simulator for flow and transport in porous media based on DUNE and PDELab.

Howto

The module dune-pdelab-howto contains a tutorial and example applications that illustrate what PDELab can do.

Multiphysics

Currently an extension of PDELab is in development that allows to couple different models in different subdomains. It consist of the following two additional modules

• dune-multidomaingrid provides a metagrid that allows to decompose a grid into several (possibly overlapping) subdomains. This module is independent of dune-pdelab.
• dune-multidomain extends dune-pdelab such that different models in the subdomains can be coupled.

Documentation

• Access the online documentation of version 2.1snapshot.
• PDELab Howto document.
• Access the online documentation of the development version.

Bug Tracking System

PDELab uses the bug tracking system available via the DUNE User-Wiki.

Mailing list

If you really cannot find your answer in either the Howto or the documentation, you might consult the Dune PDELab mailing list.
