Hi Mike, This PR deals with changes I have made in VODE for primordial chemistry. All the changes basically reflect that since we use number densities for primordial chem, we...
**Describe the proposal** We can save a lot of time by ensuring we do not do a microphysics burn (for problems that need chemistry) by masking out covered cells, when...
### Description We need to load rocm while compiling on setonix CPUs. ### Related issues Fixes #563 ### Checklist _Before this pull request can be reviewed, all of these tasks...
### Description Updating the docs to add the citation to the Quokka paper. ### Checklist _Before this pull request can be reviewed, all of these tasks should be completed. Denote...
**Describe the bug** We need `module load rocm/5.4.3` in `setonix-cpu.profile` otherwise setonix cannot find HIP. **To Reproduce** Steps to reproduce the behavior: ``` source scripts/setonix-cpu.profile mkdir build cd build cmake...
For the exact same setup, a Pop III simulation on Setonix GPUs show a very different evolution as compared to CPUs. The initial density projections on both are identical: ...
### Description Continues #20 to add gravity with subcycling ### Related issues #20 ### Checklist _Before this pull request can be reviewed, all of these tasks should be completed. Denote...
Sometimes, during regridding, the function `EnforceLimits` https://github.com/quokka-astro/quokka/blob/a37934f74c6de738321d6898906afd4a054f26bd/src/hydro_system.hpp#L703 is called with rho = 0, which then leads to NANs in the velocities, energies and pressures. I traced back the call to...
When amrex is compiled as a submodule in quokka, and quokka is compiled for AMD GPUs, this line sets `amdgpu-function-calls=false` which does not seem to be overridden even if we...
#273 implements the basic step for consistent multi-fluid advection (CMA) where we conserve the sum of mass scalars to unity. However, more stuff needs to be done during interpolation of...
