ANSYS CFX 14 on UBUNTU 12.04 64bit: PARALLEL ISSUE

david.pasquale · December 26, 2012, 20:45

hi guys,
I'm running cfx 14, pre post solver and turbogrid without any problems on a 6 core i7 machine with ubuntu 12.04 64 bit.
when I try to run the same case in local parallel i get this issue:

An error has occurred in cfx5solve:

A ANSYS CFX Partitioner executable is required for this run, but none is
available.

I already looked for this issue but i found nothing usefull...can someone help me please?
thanks in advance!

p.s from x86info i get this:

WARNING: Detected SMP, but unable to access cpuid driver.
Used Uniprocessor CPU routines. Results inaccurate.

Nobody can help me?

Can someone tell me if is able to run CFX in parallel on ubuntu 12.04 64?

Can someone tell me which version of linux 64 has no problem running cfx solver in local parallel?

THANKS!

Have you read the supported linux releases in the documentation?

david.pasquale · December 28, 2012, 07:43

yes, I know that few OS are supported...anyway I would like to understand is someone can run a local parallel run on an another linux os.
I would like also to understand which are the post-installation steps that has to be done in order to have a local parallel run.

Thanks you in advance!

You should use -partitioner command line option when starting cfx5solve. And manually point to part executable, for ex. /ansys_inc/v145/CFX/bin/cfx5solve -partitioner /ansys_inc/v145/CFX/bin/linux-amd64/int64/partitioner.exe -def $defFile -start-method "Platform MPI Distributed Parallel" -par-dist $nodes -size 1.4 $ini. Tested on Debian 7.1.

Hi everybody. I've found the same problem with CFX14 and debian wheezy. I tried to follow what suggest u22 but it doesn't work. this is the error: "Use of uninitialized value in string eq at /ansys_inc/v140/CFX/bin//perllib/CFX5/Simulation/ConfigSettings.pm line 835". Someone can help me?
thanks

Dear luigi,

Did you manage to solve this problem? I have the same problem and I would like to know how you were able to solve it.

Thanks.

Greetings from the future!

Most probably, you tried to run cfx5solve with its alias, not with the full path. This leads in 2024 still to the exact same failure message you described.
There is a cfx5solve executable also in

Code:

/mnt/software/ansys_inc/v241/CFD-Post/bin/cfx5solve

The correct executable, however, is in

Code:

/mnt/software/ansys_inc/v241/CFX/bin/cfx5solve

cfx5solve points to whatever path comes first in your path variable. So be sure to work with absolute paths or change your path variable accordingly.

Please mind! Ansys might be installed to a path different than /mnt/software. Please change accordingly.
