### 12.2.6. Running a Fluent Batch Job

You can use the built-in Fluent Batch template on the Applications panel to run a Fluent batch job. The template has been pre-configured with job submission settings that are specific to Fluent, and works with all supported job schedulers. When this template is used, Fluent is launched in server mode, which enables you to view live solution monitors and steer the solution using actions in the EKM job monitor.

1. Click the Applications icon on the title bar, and then click Fluent Batch on the Applications panel.

2. On the first screen of the job wizard, specify the tag to apply to the job (if desired), the job name, and the working directory. For details see Setting Up a Batch Job for details.

3. Click Next, then select the input files to be uploaded to the working directory. Supported file types include .cas, .dat, .cas.h5 and .dat.h5 files. For general information on uploading files, see Setting Up a Batch Job for details.

4. Click Next, then specify the Fluent job submission settings:

   For detailed information about these settings, see Starting ANSYS Fluent Using Fluent Launcher in the ANSYS Fluent Getting Started Guide.

   Version

     The version of Fluent to be used.

     The available versions in this drop-down are determined by the `solverVersions` setting in the ekm.xml file. For details see Specifying Remote Process Policies (<remoteProcess>) in the Administration Guide. Features introduced in current or recent releases of EKM, such as live job monitoring, may not be available in EKM if you choose a solver from an older release.

   Queue

     The queue on which the job will run.

     Note: Fluent jobs may fail if submitted to a queue that uses a local scratch directory. Ensure that you select a queue that uses a shared scratch directory.

   Dimension

     Choose 2D or 3D.

   Double precision

     Enable the check box to select double precision.

   Processing options

     During a Serial run, all computation is done by a single process running on one processor. A Parallel run allows you to compute a solution by using multiple processes that may be executing on the same computer, or on different computers in a network.

     Note: On Linux queues, when Parallel processing is selected, passwordless SSH access must be set up for each cluster node.

   General options

     On this tab you can specify inputs for the solution, or select an existing journal file.

     Note:

     - When selecting a Case file or Data file, you can only choose from among files that were uploaded to the working directory when you started the job.

     - When submitting a Fluent job to a Windows cluster, non-compiled UDFs are not supported.

     For a steady case, enter the desired number of iterations. For a transient case, enter the number of time steps, and the time step size in seconds.

   Environment

     On this tab you can specify other environment variables:

   Other command line options

     Specify other command line options if desired.

   Import files into repository after job completion

     If enabled, files in the job's working directory will be copied to a repository folder after the job has been executed.

     Once enabled:

     1. Click Browse to select an Output folder for the files.

     2. If you would like to import specific files or file types into the repository, specify a comma-separated list of patterns in the File patterns box, as shown in the example below. Otherwise, if you specify no patterns, all files in the working directory will be imported.

     Note:

     - This option is not available if you are working in a job-only view.

     - By default, .sum and .avz files are generated in the working directory of a Fluent job. The .sum file captures simulation details, and the .avz file captures a 3D image of the simulation model. If you choose to import .cas, .sum and .avz files, you will only see the .cas file in the repository after the import. For this type of import, EKM automatically associates the .sum and .avz files with the .cas file, and uses the data in those files to create the simulation details report and image for the .cas file.

5. Click Finish to execute the job. During the solution you can view live solution monitors and interact with Fluent using actions in the EKM job monitor. See Working with Fluent Server-mode Jobs for details.
