Hello,
I am trying to run Ansys CFX on an HPC linux cluster. I have been able to follow an example of a previous colleague who was running APDL on the same cluster and license. My .sh file looks like this: #!/bin/bash #BSUB -n 16 #BSUB -R rusage[mem=4000] #BSUB -W 1:00 #BSUB -q short #BSUB -o cfx.out.%j #BSUB -e cfx.err.%j nohup /home/badatCFX/CFX_AnsysInstall/v212/CFX/bin/cfx5 -b -p aa_r < Attempt1.def > output.out & But it is not working. Previously, the Attempt1.def file was a log file created for APDL - Does anyone have suggestions to get this script to work? Thanks in advance for saving me |

If it is not working - what is not working about it? What error message do you get?
Are you trying to run this through LSF or just from the command line? If you look in the CFX documentation you will see the syntax for the command line. For instance, the command line to run the solver is cfx5solve. Also, if you launch a command line from the CFX5 launcher it will automatically configure all the paths and variables. This is often easier than having to specify it yourself.

So I modified my script to:
#!/bin/bash #BSUB -n 16 #BSUB -R rusage[mem=4000] #BSUB -W 1:00 #BSUB -q short #BSUB -o cfx.out.%J #BSUB -e cfx.err.%J nohup /home/badatCFX/CFX_AnsysInstall/v212/CFX/bin/cfx5solve -def Attempt1.def -batch and had some windows to linux extra characters that i eliminated with the cat -v command. However, I am still getting the following errror: /home/badatCFX/CFX_AnsysInstall/v212/CFX/bin/../tools/perl-5.32.0/bin/perl: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /home/badatCFX/CFX_AnsysInstall/v212/CFX/bin/../tools/perl-5.32.0/bin/perl) I think this means I need to recompile my libc6 package?

Yes, that sounds like you are missing some libraries required for perl. This means you are running on an unsupported Linux distribution. I wish you luck
The longest thread on the CFX forum is about this: ANSYS Workbench on "Uncertified" Linux Distros Personally, the thought of running complex software like CFX on an unsupported linux distro makes me break out in hives. Even quoting that thread makes me go all itchy.

Hi Glenn,
So I have made some progress and was able to create a RedHat7 container and use an interactive session with a conda environment to get around the incompatible linux errors. However, I am now running into a licensing issue: License Cap: ANSYS CFD Solver ANSYS LICENSE MANAGER ERROR Failover feature 'CFD Solver - Level 2' is not available. FLEXlm server is not responding. Resource temporarily not available. ANSYSLI_SERVERS: 2325@~numbers FLEXlm Servers: 1055@~numbers License ID: License checkout failed (CFD SOLVER). I am trying to reference an academic license server. I have seen for mechanical a: -b -p aa_r or for CFX a license token request: -L ansys@osc:1 Any thoughts or suggestions? We have checked the communication on both ports on the license server and do accept communication from the HPC IP addresses. |

ANSYS has details on how to trouble shoot licensing issues in the installation and licensing guide. Also, I recommend using the ANSYS Client Licensing Settings app to help trouble shoot this.
