*: Current default version You can use module spider fluent to view available modules for a given machine. Feel free to contact if you need other versions for your work. Access for Academic Users Use of ANSYS products for academic purposes requires validation.

In order to obtain validation, please contact for further instruction. When you log into oakley.osc.edu you are actually logged into a linux box referred to as the login node. To gain access to the mutiple processors in the computing environment, you must submit your FLUENT analysis to the batch system for execution. Batch jobs can request mutiple nodes/cores and compute time up to the limits of the OSC systems. Refer to and for more info.

Batch jobs run on the compute nodes of the system and not on the login node. It is desirable for big problems since more resources can be used. Interactive Batch Session Interactive mode is similar to running FLUENT on a desktop machine in that the graphical user interface will be sent from OSC and displayed on the local machine. Interactive jobs are run on compute nodes of the cluster, by turning on X11 forwarding. The intention is that users can run FLUENT interactively for the purpose of building their model and preparing their input file.

Once developed this input file can then be run in no-interactive batch mode. To run interactive FLUENT GUI, a batch job need to be submitted from the login node, to request necessary compute resources, with X11 forwarding. Please follwoing the steps below to use FLUENT GUI interactivly: • Ensure that your SSH client software has X11 forwarding enabled • Connect to Oakley system • Request an interactive job.

• Compatibility of the Spalart-Allmaras turbulence model with enhanced wall treatment () • Curvature correction available, but not applicable for 2d axisymmetric geometries () • Algebraic Wall-Modeled LES available for the subgrid-scale models ( in the ) • The implementation of the Delayed DES (DDES) shielding function, f d ( in the ), has been optimized in the SST and Realizable k-ε Detached Eddy Simulation (DES) models to provide effective shielding. The constant was changed from 8 to 20.

With this change, DDES is now the recommended shielding function for the SST k-omega model with Delayed DES enabled and is used by default. • Heat Transfer. • Critical heat flux for wall boiling models available as full feature (beta feature in Release 13), including boiling model parameters () • Yao and Morel extension of the volumetric interfacial area transport model to include mass transfer and nucleation effects (beta feature in Release 13) () • Two new drag functions are available for granular flow: the Huilin and Gidaspow drag law and the Gibilaro drag law () • The Immiscible Fluid Model from previous releases of ANSYS FLUENT has been renamed to Multi-Fluid VoF Model. • The Full Multiphase Coupled pressure-velocity coupling scheme from previous releases of ANSYS FLUENT has been renamed to Coupled with Volume Fractions and is now selected by choosing Coupled in the Solution Methods task page and enabling the Coupled with Volume Fractions option (). • Eulerian Wall Film Model. Mesh Morpher/Optimizer • Ability to define the objective function that is minimized by the mesh morpher/optimizer as a custom function of output parameters, i.e., values from flux, force, surface integral, or volume integral reports () • Ability to define constraints on the boundary zones, in order to limit the freedom of particular zones that fall within the deformation region(s) during the morphing of the mesh () • Ability to specify commands that are executed before or after the calculation is run for each design stage generated by the mesh morpher/optimizer ().
