Modules software package dynamically adjusts the environment settings for using applications, by using the module command. It also makes changing the environment settings easy when switching between different versions of applications. For details, see Modules.

Version	Module File
2022R1	ansys/v221
2021R2	ansys/v212
2021R1 (default)	ansys/v211
2020R2	ansys/v202
2020R1	ansys/v201
2019R2	ansys/v192
18.0	ansys/v180
17.0	ansys/v170

You can see the list of module files available by using the module avail command.

ANSYS is a multi-physics CAE. It allows you to conduct flexible and purpose-suited analysis of physical phenomena such as structure, vibration, heat transfer, electromagnetic field, electric voltage, acousmato, thermic fluid, and drop collision, as well as problems that combine the above.

Structural analysis
Heat transfer analysis
Electromagnetic field analysis
Fluid analysis
Failure analysis
Acoustic analysis
Drop and collision analysis
Piezoelectric analysis
Coupled analysis
FSI analysis(fluid-solid coupled analysis)

Automobile
Electrical and electronic
Aerospace
Energy
Medical technology
Construction and civil engineering, etc.

You must register via the user portal before using ANSYS.

ANSYS is available only to users of Kyoto University who are physically within 50miles from Yoshida campus.

Set up the environment by using the module command. (The module file you want is loaded.)

$ module load ansys

Products are started basically from the launcher. To use launcher, enter the following command in the Exceed onDemand . For details of xrun , see Interactive Processing.

$ xrun launcher170

If you want to run a simulation by parallel execution, type -A option in running xrun to specify the number of cores.

Ex) 4 parallel execution

$ xrun -A t=4:c=4 launcher170

You must also specify "Use Shared-Memory Parallel" in the "High Performance Computing Setup" tab after the launcher has started.

You can set the simulation environment after the launcher has started.

And you can select a simulation environment from the following options. Here we explain the case ANSYS is selected.

ANSYS: ANSYS standard interface
ANSYS Batch: Used to do an analysis by a batch job

File Management Tab

Working directory
- The default save location of the file created while ANSYS is running.
Job name
- The default filename of the file created while ANSYS is running. Maximum 32 characters.

Customization and Preferences Tab

Memory
- Memory for analysis is automatically set, but it can also be set manually.
Language selection (only English for Linux and UNIX)
Graphic device
- X11: Default
- X11c
- 3D: Must support opengl
Send Output To
- Screen & File: Default
- File Only: If you are using version 2021R2 or 2022R1, please select File Only.
- Screen Only

High Performance Computing Setup Tab

Type of HPC running
- None: Serial running
- Use Shared-Memory Parallel (SMP): Thread parallelization
  - Specify the number of parallelization you want (up to 16)

After the settings are completed, click Run to start up ANSYS (in the selected simulation environment).

Changing the font size

If the default font size is smaller or larger than you expect, you can change the font size through the following menu.

[MenuCtrls] > [Font Selection]

By default, ANSYS performs the processing interactively by using a GUI, but can also be operated from the command line. The command syntax and options are listed below. For details of tssrun , see Interactive Processing.

$ tssrun ansys170 [options]  < input-file > output-file

Options	Purpose
-j JobName	Specifying a job name
-d Switch	Specifying a device type(X11, X11c, 3D)
-m Size	Specifying a memory: work space(unit: MB), it is automatically set by default.
-db Size	Specifying a memory: database space(unit: MB), it is automatically set by default.
-p Prod	Specifies a product
-g	Starts in a GUI mode
-np NCPUS	The number of parallelization
-dis	MPI parallelization
-dir Dir	Specifies a work directory

You need to prepare an Batch file to run ANSYS by Batch job. Write a script of the same commands as you execute on the command line and submit the job by the qsub command.

#!/bin/bash
#============ LSF Options ============
#QSUB -q gr19999b
#QSUB -ug gr19999
#QSUB -W 2:00
#QSUB -A p=1:t=1:c=1:m=1800M
#============ Shell Script ============
module load ansys
#
ansys170 -j test_${QSUB_JOBID} < test.dat
