Spacetime Tents in NGSolve

The ngsTents package is a c++ extension of the NGSolve finite element library, designed to ease experimentation with solvers based on spacetime tents for hyperbolic systems. A python front-end (import ngstents) allows new equations (linear or nonlinear conservation laws) to be solved by easily defining required fluxes and numerical fluxes in a few lines of code.

This documentation introduces concepts on which ngsTents are based on as well as the usage of the package. It is structured as two hands-on lecture notebooks. These lectures were first presented in an NGSolve User Meeting and were prepared by Jay Gopalakrishnan. Send all comments to gjay@pdx.edu or pull requests via ngstents repository in GitHub.
