Kernel conversion

Conversion of the kernel from ACIS (2022R2 and previous versions), to Parasolid (2023R1 and following versions) is becoming accessible to the customer, with the use of a simple script.

This script is compatible with .aedt files, as well as .a3dcomp files (including encrypted 3DComponents).

You can access the extension from the icon created on the Automation tab using the Extension Manager.

The following image shows the extension user interface:

The Browse file or folder input points to a path which is either an .a3dcomp file, an .aedt file, or a folder containing a variety of files of both types (this way the user is capable to convert the kernel of a component library with one launch of the script)

Attention: For encrypted 3D components the enable editing should be always on (with the corresponding password that is given as an input). When pointing to a library, in order for all the 3DComponents to be converted, they must have the same Application and Solution type, given as an input in the last two entries of the UI, as well as same password, in order for the conversion to be successful for all files.

Last but not least, for every file in the folder, a new file is generated in the path provided, that contains the design converted to the latest version, and its name indicating the initial file version (i.e.test_aedt_2025.1) Furthermore, for every conversion, a .csv file is created, with a name pointing to the converted design name, containing any violations that occurred during the conversion, and that need manual fixing by the user.

The following image show, the initial test_aedt and test_a3dcomp files, the corresponding .csv files and the generated 2025R1 version (with the Parasolid Kernel) files.

You can also launch the extension user interface from the terminal:

python.exe path/to/pyaedt/workflows/project/kernel_converter.py

Finally, this code shows how you can run the extension directly from a Python script:

from ansys.aedt.core.workflows.project.kernel_converter import main

main(test_args = {"password": "my_pwd",
                "application": "HFSS",
                "solution": "Modal",
                "file_path": "C:\my_path\file_containing_projects"})
