A Finite Element Analysis Program

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). These pages are intended to give basic information on the Elmer software.

FEAP is a general purpose finite element analysis program whichis designed for research and educational use. Source code of the fullprogram is available for compilation using Windows (Intelcompiler), LINUX or UNIX operating systems, and Mac OS X based Applesystems (GNU and Intel compilers).

Contact [email protected] for further information anddistribution costs.

The FEAP program includes options for defining one, two, and threedimensional meshes, defining a wide range of linear and nonlinearsolution algorithms, graphics options for displaying meshes and contouringsolution values, an element library for linear and nonlinear solids,thermal elements, two and three dimensional frame (rod/beam) elements, plateand shell elements, torsion elements, winkler foundation elements, acoustic elements,coupled problem elements, and multiple rigid body options with joint interactions.Constitutive models include linear and finite elasticity, viscoelasticitywith damage, and elasto-plasticity.

The system may also be used in conjunction with mesh generationprograms that have an option to output nodal coordinates and elementconnection arrays. In this case it may be necessary to write user functions toinput the data generated from the mesh generation program.

Any problems related to difficulties in achieving astandard installation of the programshould be addressed to: [email protected].

FEAPpv

A small version of the system, called FEAPpv, is available free of anycharge. See projects.ce.berkeley.edu/feap/feappv for additional information.This program is the companion to the books: 'The Finite Element Method, 7thedition, Volumes 1 and 2 (but not Vol 3)', authored by O.C. Zienkiewicz andR.L. Taylor and published by Elsevier, Oxford, 2013.

MATLAB INTERFACE (for older versions of FEAP)

The MATLAB interface is a standard part of versions 8.1 and later.

The MATLAB program permits easy solutions using many different algorithms.An interface for FEAP is provided by the user solution command routine'umacr3.f' below. This routine permits the output to files of the non-zerovalues contained in the residual, tangent, mass, or damping matrices.The routine is fully operational with the 7.5 release of FEAP andexcept for the unsymmetric mass and damping options with release 7.4. Theuse is quite simple. In the solution command sequence:

TANG,-1 ! Form unfactored tangent
OUTPut TANG ! Output to file 'tang' nonzero terms in tangent.

A simple MATLAB program to use the tangent is

load tang
A = spconvert(tang)

Download file from:

A direct link with MATLAB is also available. This permits FEAP to berun from MATLAB and allows for solution options available in MATLAB tobe used in the analysis process. The interface is available fromDavid Bindel at the web site listed below.

LINEAR EQUATION SOLVER INTERFACES

SGI Solver

The SGI Origin machines have multiprocessor capability and solutionof finite element problems using FEAP can be made much more efficientusing special solution packages. The routine given below providesan interface to the SGI parallel sparse solver (users must alreadyhave the solution package from SGI for this interface to function).

SuperLU Solver

An interface is available for the general sparse solver SuperLU.General information at:(http://www.cs.berkeley.edu/~demmel/SuperLU.html) Source program at (http://crd.lbl.gov/~xiaoye)

Download the source and create an archive containing the SuperLU routinesfor double precision real computations and, if necessary, the BLASroutines. (N.B. The SuperLU solver has been tested only in a Linuxand MAC OSX environment).

Next, download the following feap interface routines (zipped). Compile andlink with the main FEAP archive and those for SuperLU created as describedabove. Use solution command 'splu' to activate the SuperLU solver.Subsequent commands 'tang' or 'utan' will then use SuperLU.

UMFPACK Solver
