84 <p>OpenFOAM is developed and tested on Linux, but should work with other Unix
85 style systems. To check your system setup, execute the foamSystemCheck script
86 in the bin/ directory of the OpenFOAM installation. If no problems are
87 reported, proceed to "3. Installation"; otherwise contact your system
88 administrator.

99 <div id="text-2.1">
101 <p>The ParaView 3.3 visualisation package requires that Qt version 4.3.x MUST
102 be installed on the system. Earlier or more recent versions (4.2.x or
103 4.4.x) will NOT work. To check whether Qt4 is installed, and the version,
104 type:
105 </p><ul>
106 <li>
107 qmake &ndash;version
109 </li>
110 </ul>
112 <p>The ParaView binary executables in the ThirdParty distribution will only
113 work with PRECISELY the same version of Qt with which it was compiled. The
114 64-bit version of ParaView was compiled with Qt-4.3.1 (with openSuSE-10.3)
115 and the 32-bit version of ParaView was compiled with Qt-4.3.2 (with
116 ubuntu-7.10). If the user finds that a ParaView binary fails to run, then
117 it is almost certainly due to a conflict in compiled and installed Qt
118 versions and they will need to consult the section below on "Compiling
119 ParaView and the PV3FoamReader module."
120 </p>
122 The default versions of Qt used by some GNU/Linux releases are as follows.
123 </p><ul>
124 <li>
125 ubuntu-7.10: Version 4.3.2
126 </li>
127 <li>
128 ubuntu-8.04: Version 4.3.4
129 </li>
130 <li>
131 openSuSE-10.2: Version 4.2.1 - too old
132 </li>
133 <li>
134 openSuSE-10.3: Version 4.3.1
135 </li>
136 <li>
137 openSuSE-11.0: Version 4.4.0 - too new
139 </li>
140 </ul>
142 <p>Compilation and running of ParaView has been successful using the libraries
143 downloaded in the "libqt4-dev" package on ubuntu.
144 </p>
146 If you don't have an appropriate version of Qt installed you can download
147 the sources from TrollTech e.g.:
148 <a href="ftp://ftp.trolltech.com/qt/source/qt-x11-opensource-src-4.3.5.tar.bz2">ftp://ftp.trolltech.com/qt/source/qt-x11-opensource-src-4.3.5.tar.bz2</a>
149 and compile and install in /usr/local or some other location that does to
150 conflict with the pre-installed version.

161 <p>Download and unpack the files in the $HOME/OpenFOAM directory as described in:
162 <a href="http://www.OpenFOAM.org/download.html">http://www.OpenFOAM.org/download.html</a>
163 </p>
165 The environment variable settings are contained in files in an etc/ directory
166 in the OpenFOAM release. e.g. in
167 </p>
168 <ul>
169 <li>
170 $HOME/OpenFOAM/OpenFOAM-&lt;VERSION&gt;/etc/
171 </li>
172 <li>
173 where &lt;VERSION&gt; corresponds to the version 1.4, 1.5, &hellip;
175 </li>
176 <li>
177 EITHER, if running bash or ksh (if in doubt type 'echo $SHELL'), source the
178 etc/bashrc file by adding the following line to the end of your
179 $HOME/.bashrc file:
181 <ul>
182 <li>
183 . $HOME/OpenFOAM/OpenFOAM-&lt;VERSION&gt;/etc/bashrc
185 </li>
186 </ul>
188 <p>Then update the environment variables by sourcing the $HOME/.bashrc file by
189 typing in the terminal:
190 </p>
191 <ul>
192 <li>
193 . $HOME/.bashrc
195 </li>
196 </ul>
197 </li>
198 <li>
199 OR, if running tcsh or csh, source the etc/cshrc file by adding the
200 following line to the end of your $HOME/.cshrc file:
202 <ul>
203 <li>
204 source $HOME/OpenFOAM/OpenFOAM-&lt;VERSION&gt;/etc/cshrc
206 </li>
207 </ul>
209 <p>Then update the environment variables by sourcing the $HOME/.cshrc file by
210 typing in the terminal:
211 </p>
212 <ul>
213 <li>
214 source $HOME/.cshrc

224 <h3 id="sec-3.1">3.1 Installation in alternative locations</h3>
225 <div id="text-3.1">
227 <p>OpenFOAM may also be installed in alternative locations. However, the
228 installation directory should be network available (e.g., NFS) if parallel
229 calculations are planned.
230 </p>
232 The environment variable 'FOAM_INST_DIR' can be used to find and source the
233 appropriate resource file. Here is a bash/ksh/sh example:
234 </p>
235 <ul>
236 <li>
237 export FOAM_INST_DIR=/data/app/OpenFOAM
238 </li>
239 <li>
240 foamDotFile=$FOAM_INST_DIR/OpenFOAM-&lt;VERSION&gt;/etc/bashrc
241 </li>
242 <li>
243 [ -f $foamDotFile ] &amp;&amp; . $foamDotFile
245 </li>
246 </ul>
248 <p>and a csh/tcsh example:
249 </p>
250 <ul>
251 <li>
252 setenv FOAM_INST_DIR /data/app/OpenFOAM
253 </li>
254 <li>
255 foamDotFile=$FOAM_INST_DIR/OpenFOAM-&lt;VERSION&gt;/etc/bashrc
256 </li>
257 <li>
258 if ( -f $foamDotFile ) source $foamDotFile
260 </li>
261 </ul>
263 <p>The value set in '$FOAM_INST_DIR' will be used to locate the remaining parts
264 of the OpenFOAM installation.

272 <h2 id="sec-4">4 Building from Sources (Optional)</h2>
273 <div id="text-4">
275 <p>If you cannot find an appropriate binary pack for your platform, you can build
276 the complete OpenFOAM from the source-pack. You will first need to compile or
277 obtain a recent version of gcc (we recomend gcc-4.3.?) for your platform,
278 which may be obtained from <a href="http://gcc.gnu.org/">http://gcc.gnu.org/</a>.
279 </p>
281 Install the compiler in
282 $WM_PROJECT_INST_DIR/ThirdParty/gcc-&lt;GCC_VERSION&gt;/platforms/$WM_ARCH$WM_COMPILER_ARCH/
283 and change the gcc version number in $WM_PROJECT_DIR/etc/settings.sh and
284 $WM_PROJECT_DIR/etc/settings.csh appropriately and finally update the
285 environment variables as in section 3.
286 </p>
288 Now go to the top-level source directory $WM_PROJECT_DIR and execute the
289 top-level build script './Allwmake'. In principle this will build everything,
290 but if problems occur with the build order it may be necessary to update the
291 environment variables and re-execute 'Allwmake'. If you experience
292 difficulties with building the source-pack, or your platform is not currently
293 supported, please contact &lt;enquiries@OpenCFD.co.uk&gt; to negotiate a support
294 contract and we will do the port and maintain it for future releases.

305 (in the bin/ directory of the OpenFOAM installation). If no problems are

367 is a fairly simple process using the supplied buildParaView3.3-cvs script that
368 has worked is our tests with other packages supplied in the ThirdParty
369 directory, namely cmake-2.4.6 and gcc-4.3.1. Execute the following:
