<H2>FEAP -- Version 8.2 Released (November 2007)</H2>
<P>The distribution of FEAP version 8.2 is now available. Several =
enhancements=20
have been incoroporated in the new version. In addition a new feature =
permitting=20
parallel solutions on UNIX/Linux workstations has been added. The =
parallel=20
version requires the use of PETSc (see <A=20
href=3D"http://www-unix.mcs.anl.gov/petsc/petsc-as/">PETSc </A>) and=20
METIS/ParMETIS (see <A=20
href=3D"http://glaros.dtc.umn.edu/gkhome/views/metis/">METIS </A>). </P>
<P>FEAP is a general purpose finite element analysis program which is =
designed=20
for research and educational use. Source code of the full program is =
available=20
for compilation using Windows (Compaq or Intel compiler), LINUX or UNIX=20
operating systems, and Mac OS X based Apple systems. </P>
<UL>Contact <A=20
  =
href=3D"mailto:feap-help@ce.berkeley.edu"><EM>feap-help@ce.berkeley.edu</=
A></EM>=20
  for further information and distribution costs. </UL>
<P>A small version of the system, called FEAPpv, is available free of =
any=20
charges. See web site www.ce.berkeley.edu/~rlt/feappv for additional=20
information. This program is the companion to the books: "The Finite =
Element=20
Method, 6th edition, Volumes 1 and 2 (but not Vol 3)", authored by O.C.=20
Zienkiewicz and R.L. Taylor and published by Elsevier, Oxford, 2005. =
</P>
<P>The FEAP program includes options for defining one, two, and three=20
dimensional meshes, defining a wide range of linear and nonlinear =
solution=20
algorithms, graphics options for displaying meshes and contouring =
solution=20
values, an element library for linear and nonlinear solids, thermal =
elements,=20
two and three dimensional frame (rod/beam) elements, plate and shell =
elements,=20
and multiple rigid body options with joint interactions. Constitutive =
models=20
include linear and finite elasticity, viscoelasticity with damage, and=20
elasto-plasticity.</P>
<P>The system may also be used in conjunction with mesh generation =
programs that=20
have an option to output nodal coordinates and element connection =
arrays. In=20
this case it may be necessary to write user functions to input the data=20
generated from the mesh generation program. </P>
<P>Any problems related to difficulties in achieving a standard =
installation of=20
the program should be addressed to: feap-help@ce.berkeley.edu. </P>

<H2>MATLAB INTERFACE</H2>
<P>The MATLAB program permits easy solutions using many different =
algorithms. An=20
interface for FEAP is provided by the user solution command routine =
'umacr3.f'=20
below. This routine permits the output to files of the non-zero values =
contained=20
in the residual, tangent, mass, or damping matrices. The routine is =
fully=20
operational with the 7.5 release of FEAP and except for the unsymmetric =
mass and=20
damping options with release 7.4. The use is quite simple. In the =
