Step 1 of the openFoam installation cleared up the 'mpicc' messages

A fresh install solved GUI problem.

When I try to import .stl surface - discretizersetup shuts down

Hi Ben,

Is it an ASCII or a binary STL file? Because I think Discretizer is not able to handle binary STL files.

Hello,

I'm a german mechanical engineering student, and i want to install discretizer but i have several problems with the installation. For the first problem i have a solution. But now i have a new problem.

1. Problem - solved:

~/OpenFOAM/discretizer$ sudo gem install fxruby
Fetching: fxruby-1.6.27.gem (100%)
Building native extensions. This could take a while...
ERROR: Error installing fxruby:
ERROR: Failed to build gem native extension.
...

Solution:
You have to remove this code shred '-Werror=format-security' from this file '/usr/lib/ruby/1.9.1/x86_64-linux/rbconfig.rb'. There are two or three lines with this option.

Now 2. problem -solved:

:~/OpenFoam/discretizer$ ./discretizer.sh
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- tableio (LoadError)
from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from discretizer.rb:54:in `<main>'

Solution: You have to edit the file 'discretizer.rb'. The files which are in the same directory than discretizer.rb will be loaded in the skript, but a change in ruby will produce a failure. Because the system wide 'gem' librarys will be loaded, since ruby 1.8.x, with the command require. So you have to change the command 'require' to 'require_relative' for the files which are in the same directory than 'discretizer.rb'. That's a change in the ruby language code!

I've changed this lines:

require 'benchmark'
require 'zlib'
require_relative 'tableio'
require_relative 'objectlist'
#require "glmeshbox"
#require 'infoline'
require_relative 'dialogs'
require 'mathn'
require_relative 'methods'
require_relative 'cross'
require_relative 'mesh'

But now i have a new problem again!

If i tipe in the command line 'ruby discretizer.rb', it gives me this back:

/var/lib/gems/1.9.1/gems/fxruby-1.6.28/lib/fox16/exceptions_for_fxerror.rb:14: [BUG] Segmentation fault
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]


I'm using Ubuntu 13.04 with OpenFoam 2.2.2. I'm still using the SolidWorks CFD, but i need OpenFoam for parallel computing!
Maybe someone can help me?

kind regards,

Greetings mk2 and welcome to the forum!

And many thanks for the solution you gave for step #1, because that helped pass the biggest problem that was occuring on Ubuntu 12.10 and above!

I've finished testing the instructions adapted for Ubuntu 13.04 and made them available here: http://openfoamwiki.net/index.php/In...u#Ubuntu_13.04

Please let me know if they work for you as well!

Best regards,
Bruno

Hi,

I really would love to try out Discretizer so I would like to install it on Ubuntu 14.04. Should I go with the installation guide for 13.10 and hope for the best?

I have two versions of OpenFoam installed (of211 and of230). Will that cause problem for me? Should I do something special during installation?

Any help would be appreciated! Thanks

Hi Nat,
If you are using two versions of OpenFoam, i guess you are using "Aliases" for these two versions. Typing Alias name of a given version of openfoam or given software in terminal means that the environment of the corresponding software is called. However, these two versions of openfoam are installed separately. In my guess, you need to install discretizer twice - by going to folder of each OpenFOAM versions.

Yours Sincerely
Anil Kunwar

Hi Nat9,

Have you had any success in installing discretizer in ubuntu 14.04?
I also want to use it in ubuntu 14.04 with openFoam 4.x but my installation fails already with the download of ruby 1.8.
Or has anybody else successfully gone through that installation recently?

cheers,
Fynn
