Ansys

The Ansys engineering simulation tools are installed in both the Niagara and CC software stacks.

Getting a license

Licenses are provided by CMC Microsystems. Canadian students and faculty can register at this page.

Once you have an account, you must contact CMC and tell them you want to use the Ansys tools on Niagara, and give them your SciNet username.

Running ansys190

Example submission script for a job running on 4 nodes, with max walltime of 24 hours:

#!/bin/bash
#SBATCH --nodes=2
#SBATCH --ntasks-per-node=40
#SBATCH --time=11:00:00
#SBATCH --job-name test

module use /scinet/niagara/software/commercial/modules
module load ansys/19.0

# DIRECTORY TO RUN - $PBS_O_WORKDIR is directory job was submitted from
cd $SLURM_SUBMIT_DIR

machines=`srun bash -c 'hostname -s' | sort | uniq | awk '{print $1 ":" 40}' | paste -s -d ':'`
ansys190 -b -j JOBNAME -ppf aa_r -dis -machines $machines -i ansys.in

Running using the CC installation

Ansys 19.0

To access the CC software stack you must unload the Niagara stack.

module load CCEnv
module load ansys/19.0

You can run the script given in the previous section by substituting the previous module commands with the above two.
