pyCFS-data is a Python-based data processing framework that provides a flexible and easy-to-use toolbox for accessing, manipulating, and pre/post-processing data generated by or for use with the open-source finite element software, openCFS.
Sammanfattning
The content introduces pyCFS-data, a data processing framework written in Python to support the open-source finite element software, openCFS. The framework consists of three main components organized into submodules:
io: Focuses on reading, writing, and accessing data in the HDF5 file format used by openCFS.
operators: Provides functionality for data pre- and post-processing based on the data structures defined in the io submodule.
extras: Contains methods to interact with data stored in different file formats, such as Ansys Mechanical, EnSight Case Gold, Polytec PSV, and NiHu Matlab.
The io submodule includes a CFSReader and CFSWriter class for handling openCFS-based HDF5 files, as well as data structures like CFSMeshData, CFSResultData, and CFSResultArray for organizing mesh and result data.
The operators submodule offers various interpolation and transformation operations, such as node-to-cell, cell-to-node, nearest neighbor, and projection-based interpolation, as well as a method for fitting a geometry to a target region.
The extras submodule provides compatibility with other data formats, allowing users to read, convert, and write data in formats like Ansys Mechanical RST files, EnSight Case Gold files, Polytec PSV export data, and NiHu Matlab export data.
The framework can be easily installed, including all dependencies, via the PyPI package manager. Detailed installation instructions and comprehensive documentation are available on the project's website.
