The physics cross section data and applicability model was implemented very early in our project: the cross section construction uses some very awkward classes, the physics "construct host data" is...
Spline interpolation (or some other nonlinear interpolation) is used in Geant4 by : - Energy loss rate calculation (see `calc_energy_loss`) - LivermorePE cross sections above K-shell energy (see LivermoreElement) -...
To run large jobs on leadership-class machines, we'll need to parallelize across nodes by distributing events using MPI. A first attempt could just equally partition among tasks, but we should...
## Add maximum limit to safety If the safety is "large enough" we don't have to recalculate it. So, like `find_next_step`, we should add a maximum search distance to the...
- [x] Vecgeom crashes on GPU and produces different results from ORANGE (on host) in the stepper test - [x] `is_displaced`, `geo_limited`, `action_result` are [not orthogonal choices](https://github.com/celeritas-project/celeritas/pull/454#discussion_r924935600) - [x] range...

This is in preparation for making "views" to the optical physics data: we have at least one place where we need to "invert" a generic grid calculator. - Complete a...
**Chained on #1368** This renames `MaterialProperties` to `MaterialParams` and defines a `MaterialView` class. As discussed on slack, it also now validates that the refractive index is defined in all the...
