Trixi.jl announcement on Discourse

sloede commented 4 years ago

As per #101 and our previous discussions, we should announce Trixi.jl on Discourse in the Community/Package Announcements (?) category once #129 is merged. Here's what I propose to put in there; feel free to comment or change:

Title: [ANN] Trixi.jl: A tree-based numerical simulation framework for hyperbolic PDEs

Trixi.jl is a numerical simulation framework for hyperbolic conservation laws. A key objective for the framework is to be useful to both scientists and students. Therefore, next to having an extensible design with a fast implementation, Trixi is focused on being easy to use for new or inexperienced users, including the installation and postprocessing procedures. Its features include:

Hierarchical quadtree/octree grid with adaptive mesh refinement
Native support for 2D and 3D simulations
High-order accuracy in space in time
Nodal discontinuous Galerkin spectral element methods
- Kinetic energy-preserving and entropy-stable split forms
- Entropy-stable shock capturing
Explicit low-storage Runge-Kutta time integration
Square/cubic domains with periodic and Dirichlet boundary conditions
Multiple governing equations:
- Compressible Euler equations
- Magnetohydrodynamics equations
- Hyperbolic diffusion equations for elliptic problems
- Scalar advection
Multi-physics simulations
- Self-gravitating gas dynamics
Shared-memory parallelization via multithreading
Visualization of results with Julia-only tools (2D) or ParaView/VisIt (2D/3D)
