The Netgen 4.5 from the web location : http://www.hpfem.jku.at/netgen/
(CVS access) is used in the SMESH Module of Salome3 distribution.
How to build Netgen for Salome
1. How to build Netgen for Salome
------------------------------
Patch the netgen 4.5 distribution:
1.1. Download Netgen 4.5 from the NETGEN home site (see above).
1.2. Unpack the downloaded Netgen 4.5 archive
(hereafter we assume that this is netgen45 directory)
1.3. Patch the netgen 4.5 distribution for SALOME:
$ cd netgen45
$ patch -p1 < patch_directory/netgen45ForSalome.patch
Set CASROOT environment variable to OCCT installation path,
as Netgen 4.5 uses Open CASCADE Technology:
1.4. For 64-bit platform you also need to apply another patch:
$ cd netgen45
$ patch -p1 < patch_directory/netgen45lib64.patch
1.5. Set CASROOT environment variable to OCCT installation path,
since Netgen 4.5 requires Open CASCADE Technology:
$ setenv CASROOT <occt_installation_path>
Then run makeForSalome.sh (it will be created by the patch):
1.6. Compile and install netgen 4.5. To do this, simply run
makeForSalome.sh script (it is created from the patch):
$ sh makeForSalome.sh
