I'm completely new to Linux systems. I just started using ubuntu couple of weeks ago. The reason is, I'm running some FEA simulation on FeniCS for my dissertation. However, so far I was able to install number of softwares like ParaView and others, and started writing some FeniCS programs. Currently I'm stuck trying to install VisIt which I really really need to view and visualize this enormous output I got from FeniCS.
I downloaded VisIt 2.12.3 from here https://wci.llnl.gov/simulation/computer-codes/visit/executables
Then tried to follow many instructions to install it that I found online such as
In this page, you are told to run these 6 lines of commands
$ sudo apt-get install m4 $ sudo apt-get install mesa-utils $ sudo apt-get install libgl1-mesa-swx11 $ sudo apt-get install tcl-vtk $ sudo apt-get install libxmu-dev $ sudo apt-get install gtk2-engines-pixbuf
they run fine
after that nothing worked, although I changed the file names to match the ones I downloaded.
Anyway, I know I sound dumb and naive but can you guys give me baby steps to how to install it? I'm trying to work my way through ubuntu in order to finish my research and finally get over with this degree.
P.S. when I download Visit, two files are downloaded. One is the source file I guess and the other is a script or something
The instructions and the errors I got when followed them are:
from the link first
$ mkdir VisIt
I did and moved to that directory
2 files downloaded from VisIt webpage to that directory
I ran this command
$ chmod 755 visit-install2_4_1.sh
I got error " No such file or directory"
I matched the file naem, so I changed the command to
$ chmod 755 visit2.12.3.tar.gz
$ sudo ./visit-install2_4_1 2.4.1 linux-x86_64-ubuntu8 /usr/local/visit
error "command not found"
I tried to match the file name again
$ sudo ./visit2.12.3.tar.gz.part 2.13.3 linux-x86_64-ubuntu16 /usr/local/visit
I still got the same error. I changed the platform from ubuntu8 to ubuntu16 because I run ubuntu 16.04
