A simulations program for solving the euler equations of motion for a fluid in 2D-spherical coordinates. As of yet I am still developing the source code, adding features to it etc. It's currently bit of a mess, so I'll only upload the code that is completely finished. You'll notice that many of the separate projects/simulations/examples contain the same files. That's just me being a bit lazy with the file structure, managing each part of the code separately. Sometime in the future I'll reorganize everything to look a bit nicer, optimize and improve file structure.
The code is written entirely in Taichi, a python-embedded language that makes it possible to write parallelized code running on the graphics card, yielding much, much faster runtimes for applications that lends themselves well to for loops, like multicell simulations.
All of this is part of a school project of mine, so I didn't really have external users in mind. In the rare case that you happened to find this page by random; apologies if you don't find it user-friendly.
- 2D-Spherical coordinates
- Compressible Hydrodynamics as described by the Euler equations
- Newtonian simulation
- Simulation compatible with motion as described by special relativity
- Multiple species of molecular/atomic gases, each with its own adiabatic index Γ
- Newtonian, spherically symmetric, gravity
- Custom unit conversion (in case the numbers involved become too great for the computer to handle accurately, will have to edit manually)
- Large scale simulation!
- proton-proton chain, Branch I fusion scheme
- Quantum mechanical phenomena (electron degeneracy pressure for example)
- Photon- and ideal gas mixture
- Urca processes
- Temperature diffusion
- Make the code more modular
