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.

User Guide:

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

The previous functions are the ones that, according to our experience, are more likely to be used by a general user. However the package has more functionalities. the full API documentation for all the classes and functions is provided below.

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
