hi everybody
I have installed fluent on centos6-64bit and i receive this error:

can't exec /home/vahidss/Program/Fluent.Inc/license/lnamd64/fluentlm-helper91: No such file or directory

No error handler available
Error: Cortex received a fatal signal (SEGMENTATION VIOLATION).
Error Object: ()
Error: eval: unassigned variable
Error Object: rp-3d?

Can anybody help me please?

Ummmm, what version of Fluent are you trying to install??? Fluent has been part of Ansys for a few releases (12 onwards maybe?) now, so it shouldn't be coming up as ../Fluent.Inc/... unless you are installing a very old (6.3?).

Try installing the latest version, you should be able to download it from the Ansys website. I have Fluent 13.0 and 14.0 all working on CentOS 6.2

yes I am using Fluent 6.3

But I think it should work on Centos.
I think the problem is that I have some missed libraries.

Hi,

Have you successfully install fluent or ANSYS 14.0? I met a problem kind like that too.

My problem looks like this:

line 2863: 9468 Segmentation fault $EXE_CMD $CX_FLAGS $FL_FLAGS
The fluent process could not be started.

Hi,

I solved my problem. It has sth. to do with the DNS setup.

Cheers!

I'm having the same problem. I'm running Fluent in a VirtualBox Scientific Linux. When I've direct access to the license server everything works fine, but when I connect by VPN, I get an error like yours. I think it's a networking issue with VirtualBox but you've figured it out, so please tell us how you did it!!!

Sorry that reply you so late. I haven't check this email account for a long time.

You should check your hostname setup in /etc/hostname, make sure that it's the same with the one in your terminal. I found it is the case for my problem.

Hi, first of all, I never tried to use VirtualBox.

Second, can you do SSH to the server machine and open FLUENT with the terminal?

wallace · March 28, 2013, 13:45

Thanks for your reply. The problem appears to have been solved, but I'm not sure why. I edited a line in /etc/hosts on the guest machine and things started working fine. But then I commented out that line again and things have still been working fine since. I can't actually seem to reproduce the error any more. I guess it's a OS X / Virtualbox / Cisco AnyConnect / Scientific Linux peculiarity.

You might need to modify your file-- /etc/hosts.
Change the hostname in the file to the real hostname of your computer.
Good luck!

Yes, I add my hostname to the file (/etc/hosts) , then ,reboot. but whitout any effect.
My question is the same as vihadss‘s：
can't exec /home/vahidss/Program/Fluent.Inc/license/lnamd64/fluentlm-helper91: No such file or directory

No error handler available
Error: Cortex received a fatal signal (SEGMENTATION VIOLATION).
Error Object: ()
Error: eval: unassigned variable
Error Object: rp-3d?

This thread is specific to centos. Is your problem in any way related to centos?

When you launch Fluent you must specify the environment and whether it is 2D or 3D. In your case, that variable has not been assigned.

i.e. you usually start fluent with:
fluent 2d ...
fluent 3d ...
fluent 2ddp ...
fluent 3ddp ...

Maybe this helps:

Code:


mv /opt/ansys_inc/v182/fluent/fluent18.2.0/lnamd64/syslib/libstdc++.so.6 /opt/ansys_inc/v182/fluent/fluent18.2.0/lnamd64/syslib/libstdc++.so.6_old

 
cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /opt/ansys_inc/v182/fluent/fluent18.2.0/lnamd64/syslib/.

You have to adjust the path to your fluent installation.
