Yes, on Windows 7 I have Workbench 14.5.7 also working. It seems to be a "Linux-Problem".

I the last weeks I tried to install the WB 14(.5) on different notebooks (dell M6300 with NVidia FX 1600M, Fujitsu E743 with Intel HD4000) and desktop computers (i7 with AMD Firepro V3900, ATI HD 7750) to test different hardware and software configurations (CentOS 6 and Mint 15). While it was possible to get WB 13 running on all machines, WB is not working in all cases. Even on an old Xeon-Workstation with redhat 5 I got graphic issues.

I don't like it, but maybe I have to switch to Windows to get a new version of the WB.

Yes, this is also a possible solution.

However, I use a (non parallel) Academic License and I have heard that the new version of the workbench should allow to parallelize the meshing tool (up to 4 cores). Is this correct? In version 13 I can only use one core for meshing, while Fluent is working on 4 cores. I will test this with the Windows version. If this is not the case then I will also stay with the old version.

Do you get any other error message in the terminal? Can you launch cfx5 or cfx5pre? When I upgraded to 14.5, I got a similar error message and in the terminal I had:
No protocol specified - Cannot open X display ":0.0"

I solved this by doing:
xhost +
export display:=0.0

Not a great solution though... but it allows me to run DM and the mesher

Hassan,

It is generally very poor form to post on a public forum seeking help in breaking copyright. If you wish to use Fluent, do so under commericial or an academic license.

If you, liike myself, find that the licenses fees and such are unnecessarily prohibitive then focus your time and energy on learning an opensource CFD code. They are not what they were a decade or so ago and a few of the opensource movements in numerical computing are sufficiently mature (and are further maturing based on community involvement).

Regards

D

Dear PEM_GUY
I've already ANSYS 14.5 licence on windows, and I need only to see if there are differences in ANSYS on window and linux

Hi Hassan,

In that case, go to the Fluent site and download the binary files meant for linux. The method of installation for a linux O/S is detailed in the install instructions on Fluent's portal website.

If you run into issues - feel free to post back here and I will try to assist.

Hi,

I just walked a bit through the code auf ansys_inc/v[14|15].*/CFX/bin/cfx5arch
because everytime users of our clusters reported some errors about missing partitioner for the architecture...

in this file you will find near line 197:
Code:
     if test -n "$libc_file"; then
       case `basename $libc_file | sed 's/\.so//g'` in
         glibc-*|libc-[0123].*) # this is almost certainly a glibc version
after that I added:
Code:
           libc_file_tmp=`echo $libc_file | sed -e 's/x86_64-linux-gnu//g'`
and modified the following line from:
Code:
 libc_version=`echo $libc_file | sed -e 's/^[^-]*-//' -e 's/\.so//g'`
to
Code:
 libc_version=`echo $libc_file_tmp | sed -e 's/^[^-]*-//' -e 's/\.so//g'`
Especially Debian-based multiarch distributions have their libc in /lib/x86_64-linux-gnu/ instead in /lib/
So that regular-expression for fetching the libc_version misses because of the two hyphens in x86_64-gnu-linux...
After that modification everything seems to be fine...

To get rid of this error message I had to:To make sure the libX11 library was loaded when I started workbench I used LD_PRELOAD:
  • export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libX11.so:$LD_PRELOAD; runwb2 -oglmesa
It looks like I'll have to play similar games to get glx (i.e. libGL) working, e.g.:
setenv LD_LIBRARY_PATH /usr/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH



Ian
I upgraded the above packages and yet it did not resolve the issue any more ideas?

I am running ubuntu 12.04 x64 and Ansys 14 x64.

thanks alot!

Do your upgraded libraries have XGetRequest in them? If you are still getting errors about XGetRequest and libXext you can't have installed the right libraries.

I would seriously consider trying SuSe Linux 12.x as the libraries are closer to those used by ANSYS. My recent experience though is that even when I did get it all running under SuSe Linux, there are bugs in the Linux version for example:
* There are geometries that mesh fine with CutCell meshing on an old 32bit windows machine but will not mesh in 64bit Linux.
* I have often destroyed case files by creating them in Linux then opening them in windows and opening them in Linux again. This seems to corrupt the ANSYS DesignModeller and Meshing saved files.

I currently do my geometry and meshing in windows but run the Fluent jobs on the linux cluster without using Workbench. I won't be meshing in Linux until v15. I hope they've made some progress by then with Linux support because if they haven't I'll be ready to switch to OpenFOAM and stop paying for licences..

@irw thank you for the useful information you provided!
Yes since the Lab I prepared all has ubuntu 12.04 x64 bit I dont have time to switch to SuSE.

Below packages were the upgrade:

ii libxext-dev 2:1.3.2-1 X11 miscellaneous extensions library (development headers)
ii libxext6 2:1.3.2-1 X11 miscellaneous extension library


ii libx11-6 2:1.6.1-1ubuntu1 X11 client-side library
ii libx11-data 2:1.6.1-1ubuntu1 X11 client-side library
ii libx11-dev 2:1.6.1-1ubuntu1 X11 client-side library (development headers)

readelf -s /usr/lib/x86_64-linux-gnu/libX11.so | grep XGetRequest
234: 000000000003ec80 200 FUNC GLOBAL DEFAULT 11 _XGetRequest


readelf -s /usr/lib/x86_64-linux-gnu/libXext.so | grep XGetRequest
25: 0000000000000000 0 FUNC GLOBAL DEFAULT UND _XGetRequest

I still don't know why on earth it is still "UND" after the upgrades.

The libX mailing lists have a very brief comment about this bug:
http://lists.x.org/archives/xorg/2012-June/054482.html

I think you need to get exactly the right version of libX11 and libXext installed. I installed libX11 v1.50 and libxext v1.3.1.

However, I have a problem when starting Ansys APDL which might have sth. to do with x11 libs: The Keyboard does not work, neither in the launcher window nor in the command line of APDL. However, the keyboard works when I open a menu from the main menu, e.g. create keypoint; within these new popped up windows the keyboard is working.

Does anybody encountered this problem or knows where the problem is? I assume it has sth. to do with xorg x11?

Best,

hey everyone i'm trying to configure an Ubuntu server with the ansys package, we have academic ansys working over w7 but we are trying to configure a solver server

the key feature is the RSM program, but for us just doesn't run (not even the rsmwizard file or any other file of the rsm folder)

anyone know if it's required an special lib to work on Ubuntu?

I solved by creating a soft link to libc.so.6 under /lib. I have Fluent v13 running on Ubuntu 11 x64.
This is actually what I did:

sudo ln -s /lib/x86_64-linux-gnu/libc.so.6 /lib/libc.so.6
When the error message disappears, it shows you info about your processors. So I GUESS it's OK if you don't fix this at all.
Thanks, lihuang! We've done something similar for Ubuntu 12.04 64-bit, except we placed the symlink in /lib64:
Code:
sudo ln -s /lib/x86_64-linux-gnu/libc.so.6 /lib64/libc.so.6
Without this symlink in place there seems to be an impact on performance, so I don't think it is purely cosmetic. Watching CPU usage graphs one can see a dip at the end of every iteration.
