Aqwa Batch Execution Locating The Executable

Locating the Executable (+4)

Locating the Executable

# Find the AQWA executable (path varies by installation)
find /ansys_inc -name "Aqwa" -type f 2>/dev/null

# Typical Linux path (v2025 R1)
AQWA_EXE=/ansys_inc/v251/aqwa/bin/lnx64/Aqwa

# Confirm it exists and is executable
ls -la ${AQWA_EXE}

Directory is lnx64 on most installations. Verify on your site — may also be lnamd64.

Running AQWA

# Standard (fresh) run — program type determined by .DAT JOB card
${AQWA_EXE} std <jobname>

# Restart run (continue from previous stage)
${AQWA_EXE} restart <jobname>

<jobname> is the .DAT file base name without extension. All output files are written to the working directory as <jobname>.*.

Command File for Sequencing Multiple Jobs

# Create a .com file listing jobnames, one per line
echo -e "stage1\nstage2\nstage3" > mylist.com

# Run all jobs in sequence
${AQWA_EXE} std mylist.com

Checking Exit Status and Success

${AQWA_EXE} std analysis
# Exit code is unreliable — check output files instead:

if grep -qi "error\|fatal\|abort" analysis.mes 2>/dev/null; then
    echo "AQWA FAILED — check analysis.mes and analysis.lis"
    exit 1
elif [ -f analysis.res ] && [ -f analysis.plt ]; then
    echo "AQWA SUCCEEDED"
else
    echo "AQWA INCOMPLETE — check analysis.mes"
    exit 1
fi

echo "=== Stage 1: AQWA-LINE (diffraction) ==="
# JOB card in ${JOBNAME}.DAT must read: JOB analysis LINE

# Separate .DAT with JOB card: JOB analysis NAUT + RESTART 3 3

# (edit RESTART record to 3 3 and JOB code to NAUT before running)
