ANSYS AVZ Exporter

Batch tool for exporting ANSYS CDB + RST results into AVZ visualization format using ANSYS Mechanical automation.

---

Overview

This tool automates the workflow:

ANSYS DB → CDB → Mechanical → AVZ → AVZM (optional)

It is designed for batch processing of multiple simulation jobs and supports flexible configuration via CLI.

---

Features

• Batch processing of multiple jobs
• Automatic CDB generation from DB
• Auto-detection of unit system from /UNITS
• RST time-step probing via ANSYS DPF
• Flexible time selection: LAST, INDEX:n, VALUE:t
• Predefined and custom result sets (Total Deformation, Equivalent Stress, Strains)
• Optional AVZM bundle creation
• Fully CLI-driven workflow

---

Architecture

Python (CPython)
  ↓ Generates IronPython script
ANSYS Workbench (RunWB2)
  ↓ Mechanical execution
AVZ export

Requirements

• Windows
• ANSYS Workbench / Mechanical
• ANSYS MAPDL
• ANSYS DPF (ansys.dpf.core)
• Environment variable: ANSYS###_DIR

Usage

Basic example

python export_avz_from_rst.py ^
  --base D:\ANSYS_jobs ^
  --list out_list.txt ^
  --version 241 ^
  --units-out BIN ^
  --time LAST

Time selection options

Format	Description
LAST	Last available step
INDEX:5	Step by index
VALUE:0.25	Closest time value
0.25	Same as VALUE:0.25

Custom results

--results-preset custom ^
--results-list "Total Deformation,Equivalent Stress"

Quick start (Windows)

ExportToAVZ.bat

---

Output

• .avz files — one per result
• .avzm bundle — optional zip archive
• *_export_status.json — status report per job

---

Notes

• mech_export_avz.ipy is required for execution inside Mechanical
• The tool does not include ANSYS data files
• Designed for engineering automation workflows
• Compatible with legacy (pre-PyAnsys) workflows (Ansys 2022)
