This folder contains individual model directories, each equipped with a Python script to calculate the wall velocity specific to that model. Additional files within each model directory support the computation of matrix elements and collision integrations.
Each model directory includes the following files and subdirectories:
<nameOfModel>.py- Contains the model definition and the commands for finding the wall velocity.<nameOfModel>Config.ini- An optional configuration file containing model-specific configuration settings. (Note: This file is not included for the Yukawa model.)exampleCollisionDefs.py- Defines collision generation settings specific to the model.MatrixElements/- A subdirectory holding scripts (with .m extensions) used for generating matrix elements, as well as a .json file containing the computed matrix elements.CollisionOutput_N<spatialGridSize>/- Subdirectories for storing collision data files for each pair of out-of-equilibrium particles, with each folder corresponding to a specific spatial grid size.
Additionally, the Models folder contains a common utility file:
wallGoExampleBase.py- This script provides a shared template for wall velocity computations. It is used by all models except the Yukawa model.
The examples can be run directly with e.g.
python3 Models/SingletStandardModel_Z2/singletStandardModelZ2.py
For models that use the common `wallGoExampleBase.py', additional command line arguments are available to (re)calculate matrix elements and collisions, and adjust the momentum grid size e.g.
python3 Models/SingletStandardModel_Z2/singletStandardModelZ2.py --recalculateMatrixElements --recalculateCollisions --momentumGridSize 5
Running the model files requires a valid installation of WallGo . Generation of new matrix elements and collisions furthermore requires installations of WallGoMatrix and WallGoCollision respectively.
