For submitting a fluent job, you need to create a journal file, which contains the commands that fluent should run. You can submit a fluent job for the journal file my_journal_file.jou with the following command.
bsub [LSF options] "fluent [fluent options] -i my_journal_file.jou"
Here you need to replace [LSF options] with LSF parameters for the resource requirements of the job. Please find a documentation about the parameters of bsub on the wiki page about the batch system. Note that for parallel jobs, it is sufficient to use the -n option of bsub. The batch system will automatically set the fluent parameter for specifying the number of cores, based on the value that you specify for -n. Please find below some description for the command line parameters, the are in the submission command specified as [fluent options].
|-cc||Use the classic color scheme|
|-env||Show environment variables|
|-mesher||Start Ansys Fluent in meshing mode|
|-nm||Don't display mesh after reading it|
|-post||Start the Ansys Fluent post-processing-only executable|
|-rx||Specify realease number|
A typical Fluent job submission could look like the following:
bsub -W 8:00 -R "rusage[mem=2048, scratch=2048]" "fluent 2d -i fluent_case.jou > output.out"
In fluent, you can choose between single and double precision solvers. The choice can be specified via the parameter that indicates if the model is two or three-dimensional. In this example command, ouput is redirected to the file output.out.
|2d||two-dimensional model single precision|
|2ddp||two-dimensional model double precision|
|3d||three-dimensional model single precision|
|3ddp||three-dimensional model double precision|
