'''Description:''' CalculiX is a package designed to solve field problems. The method used is the finite element method.

With CalculiX Finite Element Models can be build, calculated and post-processed. The pre- and post-processor is an interactive 3D-tool using the openGL API. The solver is able to do linear and non-linear calculations. Static, dynamic and thermal solutions are available. Both programs can be used independently. Because the solver makes use of the abaqus input format it is possible to use commercial pre-processors as well. In turn the pre-processor is able to write mesh related data for nastran, abaqus, ansys, code-aster and for the free-cfd codes dolfyn, duns, ISAAC and OpenFOAM. A simple step reader is included. In addition external CAD interfaces like vda_to_fbd are available. The program is designed to run on Unix platforms like Linux and Irix computers but also on MS-Windows.

The CalculiX package was developed by a team of enthusiasts in their raw spare time. They are employees of MTU Aero Engines in Munich, Germany which granted the publication.

==Build Directions==

To build Calculix from the source code (necessary to use custom UMAT's) on Linux, follow the steps given.

<ol>
<li>Get the prerequisite ARPACK</li>
 <ol>
 <li>Download [http://www.caam.rice.edu/software/ARPACK/ ARPACK], or,</li>
<pre>
wget http://www.caam.rice.edu/software/ARPACK/SRC/arpack96.tar.gz
wget http://www.caam.rice.edu/software/ARPACK/SRC/patch.tar.gz
</pre>
 <li>Unpack the two files</li>
<pre>
tar xzvf arpack96.tar.gz
tar xzvf patch.tar.gz
</pre>
 <li>Edit the makefile "ARmake.inc"</li>
  <ul>
  <li>Change the <code>home</code> directory to the directory where you extracted ARPACK</li>
  <li>Change the definitions of <code>MAKE</code> and <code>SHELL</code> to be simply <code>make</code> and <code>sh</code>, respectively, with no paths</li>
  <li>Change the Fortran compiler to your version by changing the <code>FC</code> variable. The GCC version of <code>gfortran</code> worked as of version 5.4.0.</li>
  <li>If you are using <code>gfortran</code> remove <code>-cg89</code> from the line <pre>FFLAGS	= -O -cg89</pre>
  </ul>
 <li>Edit the file "UTIL/second.f", adding a "*" to the front of the line <pre>      EXTERNAL           ETIME</pre>
 <li>From the directory "ARPACK", type <code>make lib</code> in the command line.
 </ol>
<li>Get the prerequisite SPOOLES</li>
 <ol>
 <li>Download [http://www.netlib.org/linalg/spooles/spooles.2.2.html Spooles], or,</li>
<pre>
wget http://www.netlib.org/linalg/spooles/spooles.2.2.tgz
</pre>
 <li>Unpack SPOOLES into a subdirectory</li>
<pre>
mkdir SPOOLES.2.2
mv spooles.2.2.tgz SPOOLES.2.2
cd SPOOLES.2.2
tar xzvf spooles.2.2.tgz
</pre>
 <li>Change the compiler version in "Make.inc" to your compiler (gcc 5.4.0 worked: <code>CC = gcc</code>) on the line</li>
<pre>  CC = /usr/lang-4.0/bin/cc</pre>
 <li>Build the SPOOLES library</li>
<pre>make lib</pre>
 </ol>
<li>Get [http://www.dhondt.de/ Calculix]</li>
 <ol>
 <li>Download the Calculix source code, or on the command line:</li>
<pre> wget http://www.dhondt.de/ccx_2.12.src.tar.bz2 </pre>
 <li>Unpack the compressed source code</li>
<pre>
bunzip2 ccx_2.12.src.tar.bz2
tar xvf ccx_2.12.src.tar
</pre>
 <li>Edit the makefile "Calculix/ccx_#.##/src/Makefile"</li>
  <ul>
  <li>Change the variables CC and FC to the same C and Fortran compilers, respectively, used previously</li>
  <li>Change "INTEL" to "SUN4" on the line</li>
<pre>	../../../ARPACK/libarpack_INTEL.a \</pre>
  </ul>
 <li>Compile Calculix from the directory "Calculix/ccx_#.##/src/"</li>
<pre>make</pre>
 </ol>
</ol>
