Ansys

Owned by Shawn Doughty (Deactivated)
Last updated: Feb 03, 2017

Ansys is a suite of finite element based applications that provide real-world simulations of structural, thermal, electromagnetic and fluid-flow behavior of 3-D product. All Ansys products integrate with CAD environments. This is normally access via the WorkBench interface. 

Fluent is a Computational Fluid Dynamics (CFD) software package commonly used in engineering education for research in fluid mechanics. ANSYS purchased Fluent recently and has incorporated Fluent functionality into Ansys on an ongoing basis. The Ansys WorkBench product is how you access this functionality. Note Fluent 2d and 3d and Icepak products are available outside of WorkBench.

 

Ansys and Fluent related:

Now that Ansys purchased Fluent, how does one access Fluent functionality?
Most Fluent functionality is incorporated into Ansys WorkBench.

How do I run Ansys WorkBench interface?

-bash-3.2$ module load ansys
-bash-3.2$ srun ... runwb2

 

How can I read Ansys/Fluent/WorkBench and other docs while on the cluster?
You may run the Ansys Help application after you set up the module by:

-bash-3.2$ module load ansys/16.2

-bash-3.2$  srun --pty --x11=first -p interactive -c 1  anshelp162

Documents are version specific.

 

How do I run ansys in batch mode without using the Launcher if I already have an Ansys .dat file prepared?

> module load ansys/15

> sbatch   --wrap="ansys150  -c 4   -j vm233   -b  < vm233test.dat"

Where can I find example ansys files?  Various directories for different versions are available.

/opt/shared/ansys_inc/v130/ansys/data/models/

 

 

The following Fluent related info may no longer work due to Ansys incorporation of Fluent into WorkBench.

How do I run a Fluent 2D parallel job?
Define the number of cpus(up to 8) within the bsub and fluent command line. The -n and -t arguments is the location to change the number of cpus.

-bash-3.2$ sbatch  ....sbatch_options  --wrap="fluent 2d -g -t8 -pib -mpi=intel  -i yourfluent.script"
Note: replace 2d with the appropriate fluent product, such as 3d and so on...

How can I view the Fluent docs?
> module load fluent
> firefox file:///opt/Fluent.Inc/fluent6.3.26/help/index.htm

 

How do I get fluent command line options?
-bash-3.2$ srun ... fluent -help

How do I run the 2D or 3D fluent without asking the questions interactively?
-bash-3.2$ srun ... fluent 3d

How do I run Icepak?
Icepak is available from within Ansys WorkBench interface and as a command line standalone application. Start WorkBench in the normal fashion, as above. Icepak will be a choice on the Components Pane, click on it and then click setup. To run just the Icepak interface try:

-bash-3.2$ module load ansys
-bash-3.2$ srun ... icepak
