I successfully installed ANSYS 12.1.1 on my SLES 10 SP 1 system (64bit Opteron).
I tested the workbench (design modeler (DM) and meshing application) with small test-cases like meshing a cube. It worked well. But then I tried to import a big model from a windows platform (about 10 million elements). The DM worked well but when i tried to mesh it with the meshing application it displayed the following message:

A software execution error occurred inside the mesher. The process suffered an unhandled exception or ran out of usable memory.

Actually, my machine has 64GB memory this should be more than enough
I am afraid the workbench cannot allocate the physical available memory for some reason. Maybe there is a hidden parameter which enables the workbench/mesher to allocate more memory?
Or is there any special procedure to convert workbench models from windows to linux which should be kept in mind? I just copied the files from one system to the other.

By the way, the mesher worked well on the windows platform with a coarse grid. However, for the fine grid i need the big linux machine.

Does anybody experience a similar problem? I appreciate any hint .

It can handle 64GB of RAM fine. You need to log a call with support to let them help you work out why it is not working.

ANSYS 19.1 installation on Linux

I have been trying to install ANSYS 19.1 on Linux for half day, and it remains at 89% of the installation for so long. It may be some errors because the administrator of the cluster have tried too and had the same problem.

It would be great if someone could help me to solve this problem.

Comments

Please provide the output of

Then, refer to the Linux Installation guide Chapter 2 : Platform Details . This Chapter would list all prerequisites for different OS level. Make sure that the prerequisites are installed.

Also, don’t install it on your home directory. Ask your cluster admin to install it in the directory that’s accessible by any users.

Here is the output

CentOS Linux release 7.4.1708 (Core)

PRETTY_NAME=»CentOS Linux 7 (Core)»

CPE_NAME=»cpe o:centos:centos:7″

CentOS Linux release 7.4.1708 (Core)

Do I need install all the libraries indicated in CentOS 7.3 even if my version is 7.4.1708? I can’t use sudo; how could I install the libraries?

I am reading that chapter to check what I am missing, but at this moment I need to install in my home directory because the cluster admin spent a day trying to install in the directory that’s accessible by any users without any luck, and he is not willing to spend more time, so if this works in my home directory he will scale up.

How To run ANSYS Release 13.0 Workbench on 64-bit Linux

Getting ANSYS Workbench up and running on Linux at R13 is pretty simple. You just have to make sure that a few things are in place and some packages are loaded. Then it works great. Here is a quick HOW-TO on getting things going:

Pre-Install Tasks

Install CentOS 5.3 or greater or RHEL5
- Download and install the latest graphics card drivers for your video card. Restart
Next, Gnome Desktop Environment is required for optimum use.

Next, Using the Linux Package Manager. Select the Development main group and then select the additional libraries all needed. (see images below)

Select Optional packages and then select the additional MESA libraries (see below).

Next, select the Base System main group, then X Window system, and Legacy Software Support. With Legacy software support still selected. Click Optional Packages and select the additional package – openmotif22 and click close.

Post ANSYS Install Setup Tasks

Within your Terminal session. Type ProductConfig.sh

Click Configure Products, then select the products to configure or reconfigure

Pro/E Configuration GUI

Unigraphics NX install Configuration GUI

Click Continue and the product configuration script will run.

How to launching ANSYS Release 13.0 Workbench

Open a Linux terminal session:
Change your path to include /ansys_inc/v130/Framework/bin/Linux64

Next, launch the program by typing ./runwb2 and press enter

Hi everybody,
since I had a lot of issues installing Ansys on Ubuntu, I summarize here all the steps (some picked up inside this forum) that are required to have a running version. I suggest to use standard MESA driver instead of nvidia or AMD drivers because I also need to use xrdp 0.9.4 (to have remote access) and it does not work with those drivers.

The required packages from the installation guide (for RedHat/CentOS) are:
• libXp.x86_64
• xorg-x11-fonts-cyrillic.noarch
• xterm.x86_64
• openmotif.x86_64
• compat-libstdc++-33.x86_64
• libstdc++.x86_64
• libstdc++.i686
• gcc-c++.x86_64
• compat-libstdc++-33.i686
• libstdc++-devel.x86_64
• libstdc++-devel.i686
• compat-gcc-34.x86_64
• gtk2.i686
• libXxf86vm.i686
• libSM.i686
• libXt.i686
• xorg-x11-fonts-ISO8859-1-75dpi.noarch
• glibc-2.12-1.166.el6_7.1 (or greater)

1. Therefore I installed:

Then answer «No» to the question.

6. From DVD1 install Ansys, launch:

Yes, drop libxp-dev. It is likely it would work without it.

because I had also to correct the RPM function there. I am running Arch Linux on a Lenovo Thinkpad X300 with Intel Graphics G965
Thank You

P.S. In a previous Installation I had found a way to fix this but now I can’t figure it out..

I thought it might be useful to share my experience installing Ansys 17.1 on Ubuntu 16.04.

I still had the issue with «Unable to resolve function glXMakeCurrent» after going through the recommended fixes too.

I managed to solve it by creating a link to the libGL library as ANSYS DesignModeller is expecting to find libGL.so.1 in /usr/lib/

sudo ln -s /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so.1

You should use the libGL library specific to your computer. I found mine using:

Everything seems to work at the moment

Workbench has upgraded to workbench 2.0 after Ansys15.

If I may add my recent experience installing Ansys 18 on Opensuse Leap 42.1:

After the installation, I was facing errors of this type when starting fluent or other tools with a GUI:

The tips given here definitely helped ANSYS Workbench on «Uncertified» Linux Distros
But this way the Nvidia driver was not used which caused the programs to run extremely slow and choppy.

I figured out the only thing I needed to do instead was adding the library path to the Nividia driver. In my case this was:

Yes, I your solution is correct. I also added the following in «.bashrc» file for myself and it worked.
Mine is local installation (not root). Just to sum up here for others.

1. open bash file
$vim .bashrc

2. add the following lines at the end of file and set the path according to your installation

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/media/shoonya/Pacific/ANSYS171/ansys_inc/v171/Framework/bin/Linux64/Mesa
export FLUENT_ARCH=»lnamd64″
/media/shoonya/Pacific/ANSYS171/ansys_inc/v171/Framework/bin/Linux64/runwb2 -oglmesa

3. Source the .bashrc file (or logout)
$. .bashrc

4. run the following command (make changes according to your path of executable «runwb2»)

I’ve the same errors in ansys_inc/install.err , it seems that there is a small problem in an installation script. On my 32 bit ubuntu this does not prevent Design Modeller to work (but, as said before, Meshing does not).

For the «blank graphics screen» problem in Design Modeller on my 64 bit distro, I found a workaround : add the following two directories in LD_LIBRARY_PATH before calling runwb2:
ansys_inc/v121/Framework/bin/Mesa
ansys_inc/v121/Framework/bin
In fact the «mono» executable called by runwb2 (an horrible windows-like programming environment, but freeware, so don’t shout at it !), should pre-load openGL libraries (more exactly their «mesa» variant) because of an environment variable LD_PRELOAD set by runwb2. Seems that it doesn’t work. Maybe it’s not transmitted to windows executables running DM or Meshing? But with LD_LIBRARY_PATH, for me it works.

I use the following script called wb2, placed in /usr/local/bin (which is in my path), to run ansys, in place of runwb2:

Sorry to hijack this post, but this seems to be the best place to post questions regarding getting CFX to work on uncertified distros. As a first note, my distro is Ubuntu 16.04 and my Ansys version is 18.2. I have used Ansys 18.2 on UBuntu 16.04: Installation Guide in order to install Ansys on my desktop. Everything in general works perfectly fine, including running from workbench or standalone.

However, I run into an issue when I attempt to perform parallel calculations using the Intel MPI method (both local and distributed). Namely, the issue seems to be when writing results. The calculations are performed perfectly fine as I can view the residuals in the Solver Manager and they behave exactly as they do in serial. The issue is when it comes to writing the results file, the solver hangs indefinitely. Checking CPU usage shows that all designated processors are working at 100%, but nothing is being done. My guess is that the slave nodes are continuously sending signals to the master node (hence why all processors are working 100%), but either the master node is not listening or isn’t there.

I know this problem is to do with the set up as using the tutorials as a case study gives the exact same problem. Furthermore, it is not an issue with using the GUI as it behaves exactly the same way if I run it from command line or not. Unfortunately, I cannot use a different parallel method as the only available one is the IBM method, but when I attempt to use it, the solver complains about a missing library (libmport.so), which a quick Google turns up no results.

Has anyone experienced something similar or have any advice of how I may fix this problem? Thank you in advance.
