Scripting in Ansys Icepak AEDT: Benefits and Challenges
Scripting in Ansys Icepak AEDT offers numerous benefits that can significantly enhance the productivity and efficiency of thermal management tasks. One of the primary advantages is the reduction in workload for repetitive tasks. By automating processes such as model generation, mesh settings, and postprocessing, users can save a considerable amount of time and effort. Additionally, scripting is object-oriented, which improves the workflow and makes the code more manageable and reusable across different projects.
However, scripting also comes with its own set of challenges. The initial learning curve can be steep, especially for those unfamiliar with programming languages like Python. Additionally, recorded scripts can often be 'dirty,' meaning they are difficult to read and understand. Despite these challenges, the long-term benefits of efficiency and streamlined operations make scripting a valuable skill in the context of Ansys Icepak AEDT.
Solution: Script Recording in Ansys AEDT
Ansys Electronics Desktop (AEDT) offers a script recording capability that simplifies the automation of tasks. This feature allows users to record their actions within the AEDT platform and then rerun the recorded code. This is particularly useful for automating simple operations without requiring manual coding. The recorded scripts can be edited and customized to suit specific needs, making the process highly adaptable. Recorded scripts can be difficult to reuse due to their complexity. PyAEDT, a Python library for AEDT, streamlines scripting by initializing AEDT objects automatically and improving error management, resulting in cleaner, more maintainable code.
To record a script in Ansys AEDT, go to the Automation tab, select Record Script, name the file, and save your workflow. Click Stop Recording when finished to save the script.
A recorded Python script begins by initializing the project, selecting the current project and Icepak design, and launching the editor.
The GetModule allows you to access the different modules of Icepak: “Analysis Setup,” “Boundary Setup,” “Fields Reporter,” “Mesh Setup,” “Optimetrics,” “Report Setup,” and “Solutions.”
A Recorded Script for Postprocessing
To demonstrate script recording in Ansys Icepak AEDT, we developed a post-processing script that creates a cut plane, generates a temperature contour, and saves the result as an image in Icepak. The recorded script includes three main modules:
- The module for creating a cut plane:
- The module to create the temperature plot
- The module to save the image file
This script was then modified to automate the creation of multiple cut planes and their corresponding temperature contour images across the entire domain, saving each image file appropriately. This task would be tedious and time-consuming if performed manually; however, by using scripting, we can automate the process, thus enhancing both efficiency and accuracy.
The following video outlines the steps involved in this example.
Ansys Benefits
For those new to scripting, Ansys provides detailed documentation and tutorials to get started. Also, PyAEDT offers a basic tutorial that demonstrates how to launch AEDT, create a new Icepak project, and perform various tasks such as assigning boundary conditions, modifying mesh settings, and creating field plots. These resources make it easier for users to grasp the fundamentals of scripting and apply them to their specific needs.
