DOLFIN User ManualHoffman, Jansson, Logg, Wellslibraries, you need to install FIAT and FFC if you want to define your ownvariational forms.Installing Libxml2Libxml2 is a library used by DOLFIN to parse XML data files. Libxml2 canbe obtained fromhttp://xmlsoft.org/Packages are available for most Linux distributions. For Debian users, thepackage to install is libxml2-dev.Installing PETScPETSc is a library for the solution of linear and nonlinear systems, functioningas the backend for the DOLFIN linear algebra classes. DOLFIN dependson PETSc version 2.3.1 (or 2.3.0), which can be obtained fromhttp://www-unix.mcs.anl.gov/petsc/petsc-2/Follow the installation instructions on the PETSc web page. Normally, youshould only have to perform the following simple steps in the PETSc sourcedirectory:# export PETSC_DIR=‘pwd‘# ./config/configure.py --with-clanguage=cxx --with-shared=1# make allAdd --download-hypre=yes to configure.py if you want to install Hyprewhich provides a collection of preconditioners, including algebraic multigrid(AMG).98
DOLFIN User ManualHoffman, Jansson, Logg, WellsDOLFIN assumes that PETSC DIR is /usr/local/lib/petsc/ but this canbe controlled using the flag --with-petsc-dir= when configuringDOLFIN (see below).Installing FFCDOLFIN uses the FEniCS Form Compiler FFC to process variational forms.FFC can be obtained fromhttp://www.fenics.org/Follow the installation instructions given in the FFC manual. FFC followsthe standard for Python packages, which means that normally you shouldonly have to perform the following simple step in the FFC source directory:# python setup.py installNote that FFC depends on FIAT , which in turn depends on the Python packagesNumeric (Debian package python-numeric) and LinearAlgebra (Debianpackage python-numeric-ext).
