<h2> A Short Intro to Elmerpost </h2>
<p>
Elmerpost is a program for displaying results from FEM analyses, primarily from Computational
Fluid Dynamics (CFD). The program has been (or rather is being) developed at
<a href=http://www.csc.fi/>CSC - IT Center for Science Ltd. (CSC)</a> as a part of the
<a href=http://www.csc.fi/CFD/elmer/>Elmer project</a>, which itself is a part of the Finnish national
<a href=http://www.csc.fi/CFD_ohjelma/vdto_eng.html> CFD Technology Programme</a> by the Technology
Development Centre of Finland (TEKES).
<p>
Elmerpost is mostly coded in C-language using primarily two tool packages outside of it's own
code: <a href=http://www.sgi.com/Technology/openGL> OpenGL</a> graphics library which can be replaced by
the freely distributable library called <a href=http://www.ssec.wisc.edu/~brianp/Mesa.html> Mesa </a>,
and the <a href=http://www.sunlabs.com/research/tcl/> TCL/TK package</a> for user interface tools.
The Elmerpost code and the tools used make this package usable in virtually any UNIX/X-environment.
The tested environments are: Linux, SGI IRIX, HPUX and DEC Unix. Windows NT/Windows95 - version has
also been tested and is working.
<p>
<h5>Elmerpost data display styles include:</h5>
<ul>
<li> Color coded mesh display
<li> Isocountour line display
<li> Isosurface display
<li> Vector display
<li> Sphere display
<li> Particle advection and streamline display
</ul>
<p>
<h5>There are also several additional features:</h5>
<ul>
<li> A matrix language MATC, which can be used to manipulate data with
<ul>
<li> Basic matrix and vector operations
<li> Dynamically sizeable variables
<li> A programming language with functions, flow control, loops, I/O, etc.
<li> Derivative operators for the finite element model: gradient, divergence, and curl
</ul>
<li> Both a graphical and command line user interface
<li> The TCL/TK environment can be used to full extent, providing a programmable
user interface tool to extend the program to specific needs
<li> Arbitrary cuts may be extracted from a 3D model
<li> Colormap editor, surface material editor, background color editor
<li> Unlimited number of user controllable views of the model
<li> A versatile clipping ability
<li> Some basic element grouping ability (at the moment not very effective use
is made of this ability)
<li> Online help in HTML format (a simple basic HTML browser is also included)
</ul>
<p>
