- Powerful for automating workflows with MSC Nastran, NX Nastran, and other variants; enables custom pre- and post-processing of FEA models and results; open-source; actively developed by a dedicated maintainer.
- Specific to Nastran users, requires understanding of Nastran file formats and conventions, learning curve for its extensive API and object model can be steep for casual users.
最适合：
- Engineers and analysts who use Nastran FEA software and want to automate their workflows, perform custom data extraction, manipulate models, or integrate Nastran results with other Python tools.
