ngstents is an c++ extension of the NGSolve
finite element library designed to ease experimentation with
tent-based methods for hyperbolic systems. The python front-end allows
new equations (linear or nonlinear conservation laws) and schemes to
be easily defined using their fluxes and numerical fluxes in a few
lines of code.
NGSolve is required
After cloning this repository, do the following:
cd cppmkdir build && cd buildcmake ..make -j4 install
Check if your installation is working by running the code in the 'tests' fodler (say, by using an automated tester like pytest).
A simple Matplotlib-based code provides visualization of a (2D) spacetime slab in this case.
Several methods are available for visualizing tent-pitched slabs in two spatial dimensions plus time:
tentswebguiallows visualization of a tent-pitched slab in a browser directly or within a Jupyter notebook.tentsngsguiis a plugin to NGSolve/ngsgui which adds a tent scene for visualizing a tent-pitched slab- The tent slab geometry can also be exported to a VTK file for viewing with Paraview.
tentsngsgui currently supports a tent-pitched slab on a 3D spatial mesh, but gives very incomplete visualization of the tents and layers.
For more details on tentsngsgui and tentswebgui, see the README.md files in their directories.
