Known Issues and Errata
This page collects current limitations, beta-status physics features, and any corrections to the published documentation or methods papers.
Beta physics modules
The following Quokka physics modules should currently be treated as beta because they have not yet been exercised in a published science application with Quokka:
| Module | Status | Notes | Documentation |
|---|---|---|---|
| Radiation | beta | Two-moment radiation transport and matter-radiation coupling | Equations, Radiation Integrator |
| Magnetohydrodynamics (MHD) | beta | Ideal MHD with constrained transport | MHD module |
| Dust | beta | Dedicated dust dynamics and dust-gas drag source terms | Dust module |
| Particles | beta | Particle-mesh gravity, sink particles, star formation, and feedback | Particles |
| Chemistry | beta | Primordial chemistry source terms | Equations, Runtime parameters |
| Self-gravity | beta | Poisson solve for gas and particle mass | Equations |
Hydrodynamics and optically-thin cooling are not currently marked as beta.
Current limitations
- Reflecting magnetic-field boundary conditions are not yet physically complete; Quokka currently applies
reflect_evento all magnetic-field components. MHD + radiationis not yet tested and is currently explicitly disabled in the code.MHD + dustis not exercised by an in-tree problem and should be treated as untested.- Dust currently neither contributes to, nor feels forces from, the gravitational potential.
Errata
No published errata are currently recorded on this page.
If you find a documentation error or a discrepancy between the documented equations and the implementation, please open an issue on the Quokka GitHub repository.
