Tutorial

This tutorial introduces how to use Ascent, including basics about:

• Formatting mesh data for Ascent
• Using Conduit and Ascent’s Conduit-based API
• Using and combining Ascent’s core building blocks: Scenes, Pipelines, Extracts, Queries, and Triggers
• Using Ascent with the Cloverleaf3D example integration

Ascent installs include standalone C++, Python, and Python-based Jupyter notebook examples for this tutorial. You can find the tutorial source code and notebooks in your Ascent install directory under examples/ascent/tutorial/ascent_intro/ and the Cloverleaf3D demo files under examples/ascent/tutorial/cloverleaf_demos/.
