Hello guys,

i installed ANSYS 17 on ubuntu 16.04. The installation works fine and i can use ICEM, CFX-Post, TurboGrid, Solvermanager ...
Only CFX-Pre doesn't work.

Everytime i try to start i get following error:

Warning: ExternalPhysicsQueries - attempt to register ExternalPhysicsInterface more than once!
Invalid float bound in "PARAMETER VALUE" data for Adaption Target Residual
terminate called after throwing an instance of 'cue::PhysicsException'
what(): Invalid float bound in "PARAMETER VALUE" data for Adaption Target Residual
An error has occurred in cfx5pre:

/usr/ansys_inc/v170/CFX/bin/linux-amd64/PreGui_ogl.exe was interrupted by
signal ABRT (6) and dumped core

Aborting due to unexpected error:
comm::error: GUIInterface::waitInput - Unexpected end of transmission from GUI.

I already tryed deleting .cfx folder, installing libmotif4, editing etc/hosts ... but nothing worked. I really don't understand the error.

Any Help would be lovely.
Thanks

as far as I know, ubuntu is not supported by Ansys. You probably have to be happy that you can start it via command line.
You might have better luck with CentOS. I am running CFX 18.1 in CentOS 7 and it works quite well.

Why support the most common linux distribution?

Ok. I installed centOS_1611 but cfxpre got the same error.

You tried to open a different model or some tutorial files in PRE, right?! I hope it's not just a problem with your model...

As far as I remember, I didn't have any problems with Ansys 17 on CentOS either but I'm doing pre- and postprocessing in Windows...
I just openend PRE (18.1) in CentOS 7.3.1611 and it doesn't show an error.

Do you have access to Ansys 18.1?
I'm afraid I can't help you more here. I would recommend checking the Linux section of this board and contacting Ansys support.

Yeah i installed ansys 18 and it worked. But i need to use ansys 17 on cluster. Now i write my .def files on a slow windows machine with 17. But now i can go on...

Fu** ansys.

Thanks 4 reply.
