[http://en.wikipedia.org/wiki/Finite_element Finite Element] Analysis is a very computational intensive technique for solving a wide range of problems.

== Non-FEM Solver tips ==
The following list of items are not related to the actual FEM solver itself. But since solvers range so widely, these tips are somewhat generic and may or may not help your specific applicaiton.

=== IO ===
FEM codes, for the most part, do a great deal of local IO. This is a result of several possibilities including the solver itself (an out-of-core solver) or retaining intermediate results to make post-processing, including stress recovery, much faster.

Based on some testing of commercial FEM codes, here are some tips for improving performance.

* Use RAID-0 for the local scratch space.
* If possible use EXT2 or XFS for the local IO

 *[http://www.physics.drexel.edu/~olson/paramesh-doc/Users_manual/amr.html PARAMESH] is a package of Fortran 90 subroutines designed to provide an application developer with an easy route to extend an existing serial code which uses a logically cartesian structured mesh into a parallel code with adaptive mesh refinement(AMR). Alternatively, in its simplest use, and with minimal effort, it can operate as a domain decomposition tool for users who want to parallelize their serial codes, but who do not wish to use adaptivity. The package builds a hierarchy of sub-grids to cover the computational domain, with spatial resolution varying to satisfy the demands of the application. These sub-grid blocks form the nodes of a tree data-structure (quad-tree in 2D or oct-tree in 3D). Each grid block has a logically cartesian mesh.
 *[http://mooseframework.org/ MOOSE ] or Multiphysics Object-Oriented Simulation Environment (MOOSE) is a finite-element, multiphysics framework primarily developed by Idaho National Laboratory. It provides a high-level interface to some of the most sophisticated nonlinear solver technology on the planet. MOOSE presents a straightforward API that aligns well with the real-world problems scientists and engineers need to tackle. Every detail about how an engineer interacts with MOOSE has been thought through, from the installation process through running your simulation on state of the art supercomputers, the MOOSE system will accelerate your research.

Elmer development was started 1995 in collaboration with Finnish Universities, research institutes and industry. Elmer includes physical models of fluid dynamics, structural mechanics, electromagnetics, heat transfer and acoustics, for example. These are described by partial differential equations which Elmer solves by the Finite Element Method (FEM).
