Ansys

The Ansys suite of programs can be used to numerically simulate a large variety of structural and fluid dynamics problems found in many engineering, physics, medical, aeronotics and automative industry applications.

• 19.2b

Use the command

$ module avail ansys_inc

to show available versions.

Connect to the interactive node mesoshared using X2GO as explained here.

Open a terminal and load the ansys_inc module:

$ module load ansys_inc/19.2b

You can then access to the all ansys software components, for example launcher, cfxsove.

To run ansys with grapical mode:

$ ansys192 -g

Batch mode will execute ansys in command line using Grid Engine batch scheduler.

In this example we will execute ansys in parallel (shared memory) using 16 cores.

• We request 16 cores (one can request from 1 to 16 cores. harware limitation)
• We use default queue
• We request 4G of memory by core i.e total 64G (the whole memory in the node).

ansy.sge

#!/bin/bash
 
#$ -N test_ansy
 
#$ -q all.q
 
#$ -pe openmp 16  ## we request 16 core # MAX is 16 (hardware limit)
 
#$ -o $JOB_NAME.$JOB_ID.out
 
#$ -l h_vmem=4G   ## we request 4G by core
 
## load ansys module
 
 module load ansys_inc/19.2b
 
## start application
 
ansys192 -np $NSLOTS -j inputansys23 < inputansys23.txt  >& inputansys23${JOB_ID}.out

Submit the script to SGE :

$ qsub ansy.sge
