Welcome to the libMesh wiki! The purpose of this resource is to promote collaboration between libMesh users. Specifically, this page is not intended to replace the mailing lists, which are the proper forum for detailed questions & discussions. This page should provide a basic knowledge base that can be used by both existing and new users and to demonstrate the capabilities of the library on betway poker.
How to learn libmesh
Documentation to libmesh is
- the source code itself and http://libmesh.sourceforge.net/doxygen/index.html
- examples http://libmesh.sourceforge.net/examples.php
- some documentation can be found at http://libmesh.sourceforge.net/presentations.php and http://libmesh.sourceforge.net/publications.php in the form of presentations
- mailing lists http://sourceforge.net/mail/?group_id=71130
- this wiki page (see the examples section)
Installation instructions with examples. Problems with installation (MPI, PETSC, SLEPC).
Results from applications that use libMesh
The only public available applications written in libmesh, so that users can learn from them, are in the examples section of the main page and here.
- A page by [Ondrej Certik] with notes and implementations of the
Other libmesh Documentation

- PETSc - http://www-unix.mcs.anl.gov/petsc/petsc-2/ - "PETSc is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations." libMesh uses a number of PETSc features to solve linear and nonlinear implicit systems on distributed memory parallel machines.
- Trilinos - http://trilinos.sandia.gov - "The Trilinos Project is an effort to develop algorithms and enabling technologies within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific problems." libMesh is now implementing support for trilinos, as an alternative to PETSc
- SLEPc - http://www.grycap.upv.es/slepc/ - "SLEPc is a software library for the solution of large scale sparse eigenvalue problems on parallel computers. It is an extension of PETSc and can be used for either standard or generalized eigenproblems"
- Gmsh - http://www.geuz.org/gmsh/ - Gmsh is an automatic 3D finite element grid generator with post-processor. Its design goal is to provide a simple meshing tool==Related Links==
cellulite for academic problems with parametric input and advanced visualization capabilities. libMesh supports both import from GMSH (including the definition of boundaries) and export for visualization.
- Paraview - http://www.paraview.org - ParaView is "an open-source, multi-platform application designed to visualize data sets of size varying from small to very large." libMesh exports the results in several formats supported by Paraview (vtk, exodus). It's a great post-processing tool.
- GMV - http://laws.lanl.gov/XCM/gmv/GMVHome.html - General Mesh Viewer is "an easy to use, 3-D scientific visualization tool designed to view simulation data from any type of structured or unstructured mesh." GMV is developed at Los Alamos National Labs and is freely available for a number of platforms. libMesh exports data in the GMV format, so if you are looking for a free visualization tool be sure to check GMV out.
- FEVal - http://developer.berlios.de/projects/feval/ - FEVal is an easy to use tool to convert FE file formats, change and renumber meshes, and postprocess FE data. It is written in Python and requires scipy (http://www.scipy.org).

- Deal.II helped inspire this project. I (Benkirk) used Deal.II in some exploratory object-oriented finite element applications back in 2001 and was impressed with its functionality. However, the need for arbitrary element types and the desire to use distributed memory parallel machines motivated the creation of libMesh.

- Impact - http://impact.sourceforge.net/ Impact is an open source finite element program which can be used to predict most dynamic events such as car crashes or metal sheet punch operations. They usually involve large deformations and high velocities.
