netgen wont import step or iges?

Hi,

I installed the caelinux 2007 to hard disk and am trying to develop some meshes with netgen. It does not seem to be able to import any step or iges files. After reading the netgen website it appears that the lateste version of netgen needs to be linked to the occ libraries and the website seems to suggest making a new install of netgen.

My question is if I install/update netgen will it break any of the other programs provided in caelinux which may call netgen as a subroutine?

The reason I want to use the latest netgen is that it seems to have a mesh coarsening capability and the step import which would be useful for me.

Thanks,

Brian R

Hello,

Perhaps a reply this late may not be very useful, but I recently installed Netgen 4.9.12 on a CAELinux 2010 64bit PC using the following:

[code:1]
sudo gedit /etc/apt/sources.list &
# deb ppa.launchpad.net/cae-team/ppa/ubuntu lucid main
# deb-src ppa.launchpad.net/cae-team/ppa/ubuntu lucid main
[/code:1]
Append the above 2 lines to the sources.list file, without the comment '#'
Add the PPA key to your keyring, install needed packages to compile Tix8.4.3, without which netgen will crash at runtime.
[code:1]
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E0BD7612

sudo apt-get update

sudo aptitude install build-essential tcl8.5 tcl8.5-dev tk8.5 tk8.5-dev glutg3 \
glutg3-dev libxmu-dev liblapack-dev

cd /tmp
wget -nd downloads.sourceforge.net/project/tix/ti.../Tix8.4.3-src.tar.gz
tar xfs Tix8.4.3-src.tar.gz
cd Tix8.4.3
./configure --with-tcl=/usr/lib/tcl8.5/ --with-tk=/usr/lib/tk8.5/
make
sudo make install
sudo aptitude install netgen
[/code:1]

Now netgen will import STEP/IGES files since the PPA version of the package has the OpenCascade capability added in.
