PySEMTools

PySEMTools is a Python package for post-processing Spectral Element Method data for fluid simulations.

The following pages contain documentation for some of the most relevant classes and functions. However, some are missing. For a complete list of classes and functions, please refer to the source code. Particularly for POD calculations.

User Guide:

• Data types
• Interpolation
• InputOutput (I/O)

---

We beleive that the easiest way to get started with PySEMTools is to use the examples provided in the repository supported by the documentation.

Most examples are in jupyter notebooks, however those that can not generaly be run in series are in python scripts.

For your convenience, we compile the jupyter notebooks here. To run them, go directly to the example folder in the repository or copy the cells you need into your python scripts.

There are more examples in the repository.

Examples on data types and IO:

• Data types and IO
• Sem subdomains
• Data compression

Examples on calculus on SEM mesh:

• Derivation
• Integration

Examples on interpolation:

• Interpolation to query points
• Element distribution interpolation
• Interpolation from 2D sem mesh
• Generating structured meshes
• Interpolating file sequences
• Visualizing pointclouds

Examples on reduced order models:

• POD from pointclouds
• POD and fft from pointclouds
• Write out data

Examples on statistics:

• Processing statistics files
• Visualize the rotated mean
• UQ of velocity fields
• UQ of temperature fields
