Installing ANSYS on openSUSE

English Applications

I want to install ANSYS on openSUSE
The platform-support-ansys-15.0-detailed-summary.pdf says that ‘ANSYS supports Red Hat Enterprise Linux (RHEL) and SUSE Enterprise Linux (SLES / SLED)’
Will ansys support openSUSE. Is there any free distro totally binary compatible to SLES like the case of CENTOS.

It also says that, ‘ANSYS does not support Fedora, Scientific Linux, Debian, Ubuntu, Oracle LINUX, etc’.

Again it says, We can not sustain certification and technical support of multiple Linux distributions
Stability issues have been encountered on some open-source Linux
We will only provide support on issues that can be reproduced on our certified RedHat
and SUSE Linux releases.

Hilarious, rotfl! they charge a premium and still cannot make a stable software

Since it looks like ANSYS puts all their support documentation including really basic technical details in their “Customer Portal” behind a password, there’s no way way to answer definitively.

You’ll either have to ask an ANYSYS partner or look up the required documentation yourself (if you have a password).

Documentation for ansys platform support http://www.ansys.com/staticassets/ANSYS/staticassets/support/r150-platform-support-roadmap.pdf http://www.ansys.com/staticassets/ANSYS/staticassets/support/r150-platform-and-hardware-support-notes-7-2014.pdf

This link http://www.padtinc.com/blog/the-focus/how-to-run-ansys-release-13-0-workbench-on-64-bit-linux describes how to install ansys on centos (centos is completely binary compatible to RHEL - as far as I know).

Is openSUSE binary compatible to SLES?

If I won’t get anything, ultimately I will install ansys and post the results here.

What’s the difference between SLES and openSUSE. Atleast the core will be same right.

Not entirely they are related but they are different. In general you will have just about everything at a different version because openSUSE moves forward faster then SUSE. That means there are new things in openSUSE that are not in SUSE. At some point SUSE will take the good things it thinks are in openSUSE and produce a new version of SUSE.

I might describe the differences in a generally that
Although the subsysems of SUSE and openSUSE are at the moment very different, in general openSUSE should still supports backwards compatibility sufficient to run apps that run on SUSE.

At a higher level, it appears that SUSE also has a number of management and configuration apps which help setup and manage apps running on SUSE which are immediately translatable to how openSUSE is setup.

I think though that your basic question is likely whether an RPM created for SUSE will run on openSUSE. I’d say likely but not guaranteed so it’s worth a try but don’t assume it’s a definite.

Unfortunately the “documentation” you reference (which I also read) is very non-technical and sparse… nothing that provides enough information to be helpful unless you follow exactly what it states (which does not mention openSUSE). I was looking for specific install and configuration steps which is apparently only available to portal members.

Hi
The document I saw indicated they only supported up to SLE 11 SP2, which
is well out of date for general support (unless you have LTSS), kernel,
glibc etc. SLE 11 SP3 has been out for a while now and SLE 12 around
the corner. Maybe the OP can ask them if/when they will support SLE 12.

Download the ANSYS installation manual from above mentioned link. I’m following it and will be referring to it as I’m able to comprehend few concepts.

  1. ** Page 131 - **
    The dependencies mentioned follow naming convention of RedHat. I tried searching in yast but I don’t get the exact packages, plus this process is tiresome. Is there any tool which will tell equivalent package name for openSUSE. So, I neglected the dependencies currently and installed the ansys. I’ve not run ansys till and I’m expecting dependency errors once I try to run it 1. **Page 132 - Semaphore Limit - **
    What is that. 1. **Page 133 - Using FLUENT with Infiniband - **
    Is the asterisk important in the expression ```
  • hard memlock unlimited
  • soft memlock unlimited
 Also, currently I'm running ansys on a laptop. Will I be required to do those changes. And, later I'm planning to install ansys on HP Z 600 workstation. Will I be required to make such changes then.
  1. **Page 151 5.1. Post-Installation Procedures for All Products**
 - 2nd point. It bounced over my head. What are they trying to say/do  1. **Page 153 5.1.1. Post-Installation Procedures for Mechanical APDL and ANSYS Workbench Products**
 - 1st and 2nd point

1st point - I don't know much about environment variables and how to set it.

2nd point - I at.allow is not present at.deny is present. man at.deny says if at.allow not present at.deny will be read. My at.deny contents

akash@akash:~> sudo cat /etc/at.deny
root’s password:
root
bin
daemon
lp
mail
news
uucp
games
man
wwwrun
ftp
nobody


What changes should I make

Other problems - To be continued . . . ;)

Hi
Page 131
A user has them packaged for 13.2;
http://software.opensuse.org/package/openmotif22-libs

Page 132
You need to look at sysctl.conf to tweak the kernel options.

Page 133
Are you using MPI? Don’t think you will run into issues if you change
it, try and see what happens…

Page 151 5.1
Add the required options into the ~/.profile seems pretty clear?

Page 153
You can add into the .profile things like export
ANSYS145_DIR=/some/path as you require.

In a terminal you can echo $ANSYS145_DIR to see what it is our use the
env command should show what they are.

With respect to at command
That’s to start jobs at a specified times for your user, you should not
need to change anything, it’s just a oneshot version of cron…
