Tallies on Unstructured Meshes

---

Keeps track of the distances traveled by particles in each mesh elements to be used for tallies with tracklength estimators.

Features

• Pumi-PIC and Kokkos Based (GPU and OpenMP parallelism)
• Distributed Mesh and Tallies with Omega_h

---

Working Principle

The workflow is consisted of three steps:

1. Copy origins and destinations and other necessary data of particles from the monte carlo transport code.
2. Move the particles to the destination.
3. Tally the particles.

The following diagram shows the workflow in detail:

Compilation

Needs the following dependencies:

1. Pumi-PIC

Important

Only the add_functor_to_search_mesh branch will work on this. It can be compiled as directed by PumiPIC Wiki.

2. Catch2

Note

Only when testing is enabled.
