More Details

This repository statically serves a Xeus Python Jupyter lite Web assembly environment wth most of the Python API for OpenMC preinstalled. The execution of code within the Jupyter notebook is performed locally within the sand boxed environment, not on a remote server. For more details see the excellent Xeus-python-demo github repo

There are a few current limitations:

• The OpenMC executable is not included so you can't actually run OpenMC simulations. To include this OpenMC would need compiling for Webassembly with emscripten or similar.
• h5py is also not available in the environment so you can't load h5 cross sections. This is due to h5py distribution not meeting the packaging requirements of either being a no-arch packages from conda-forge or an emscripten-forge package.
