 +====== ANSYS FLUENT in batch ======
  
 +ANSYS FLUENT is commercial software that may only be used by research groups running a private license server.  You must know the port and license server name to run this example. 
 +
 +===== Submitting job =====
 +
 +
 +Copy a Grid Engine script file and all necessary input files to your working directory, and then
 +
 +  - Login headnode.
 +  - Start workgroup shell.
 +  - Change to your working directory.
 +  - Submit the job.
 +
 +<note tip>
 +Sample commands here demonstrate example for : (cluster ''mills.hpc'', user ''traine'' in workgroup ''it_css''). However, same commands are also applicable for cluster ''farber''
 +</note>
 +
 +<code>
 +ssh traine@mills.hpc.udel.edu
 +workgroup -g it_css
 +cd /lustre/work/it_css/users/traine/fluent
 +qsub fluent-3ddp.qs
 +</code>
 +
 +The working directory ''/lustre/work/it_css/users/traine/fluent'' has the
 +Grid Engine script file ''fluent-3ddp.qs'' that starts FLUENT with the input file with instructions to read the case file, run a solver and write the solution data file. FLUENT's log files, data files and script output files will be stored in the working directory after the job completes.
 +===== Downloading example =====
 +
 +An example that shows how to submit a batch mpi job to execute fluent 3ddp with an input journal file can be downloaded from
 +the link: [[http://www.udel.edu/it/research/files/cluster/fluent-3ddp-mpi.tar.gz|fluent-3ddp-mpi.tar.gz]]. 
 +
 +On Mills, the commands
 +<code bash>
 +wget http://www.udel.edu/it/research/files/cluster/fluent-3ddp-mpi.tar.gz
 +tar -zxf fluent-3ddp-mpi.tar.gz
 +</code>
 +will get and extract the files to the directory ''fluent-3ddp-mpi'', with the files:
 +  - **''fluent-3ddp.qs''** — Grid Engine script to execute ''fluent 3ddp'' with input file: ''input-3d''
 +  - **''input-3d''** — Fluent journal input files with the command to read ''3d.cas''
 +  - **''3d.cas''** — Fluent case file.
 +
 +<note important>
 +ANSYS/fluent is a licensed product, so you must export a valid value of the ''ANSYSLMD_LICENSE_FILE'' variable to gain access to fluent on Mills.
 +The exact value should be obtained from the owner of the license.  Without a proper value, the script output will contain a message such as:
 +<code text>
 +ANSYS LICENSE MANAGER ERROR:Could not connect to any license server. 
 +The server is down or is not responsive. 
 +</code>
 +</note>
 +
 +===== Running example =====

 +Sample session from login to submission:
 +<code text>
 +wombat:~ jdoe$ ssh traine@mills.hpc.udel.edu
