WarpX Simulation Models

The active WarpX inputs are organized by model:

simulations/
  inputs/
    model_1_hicks_proton/
    model_2_superposition_proton/
    model_3_superposition_proton_electron/
    model_4_poisson_proton_electron/
  outputs/
    model_1_hicks_proton/
    model_2_superposition_proton/
    model_3_superposition_proton_electron/
    model_4_poisson_proton_electron/
  run_model.sh
  make_particle_movie.py

Each model folder contains input.txt and a small run.sh shim that calls the shared launcher.

Models

• model_1_hicks_proton: proton tracer model with the Hicks effective ponderomotive particle field. The proton species is named ions in the WarpX deck and does not deposit charge.
• model_2_superposition_proton: proton tracer model with the analytic finite-electrode superposition RF particle field. The proton species is named ions and does not deposit charge.
• model_3_superposition_proton_electron: quasi-neutral proton/electron model with the analytic finite-electrode superposition RF particle field plus self-consistent electrostatic fields from charge deposition. The timestep is fixed at 1.0e-10 s, so the fastest electron timescales are intentionally not resolved. The electrostatic domain uses grounded PEC field boundaries so the Poisson solve remains compatible after absorbing particle boundaries leave a net charge.
• model_4_poisson_proton_electron: quasi-neutral proton/electron model with 16 conducting embedded-boundary RF electrodes. Electrode fields and plasma self-fields are solved together by the electrostatic Poisson solve with the same fixed 1.0e-10 s timestep. It uses grounded PEC outer field boundaries so the Poisson solve remains compatible after absorbing particle boundaries leave a net charge.

Running

Activate the WarpX environment first, then run from inside a model folder:

cd /Users/thibaultclavier/report/simulations/inputs/model_1_hicks_proton
./run.sh

The launcher accepts the same movie options and WarpX command-line overrides:

./run.sh --no-movie
./run.sh --movie-fps 16 --movie-max-frames 200
./run.sh max_step=20 stop_time=2.0e-8 diag1.intervals=1

Every launch creates the next numbered output directory:

simulations/outputs/<model_name>/simN/

Each simN contains diags, warpx_used_inputs, warpx.log, and, when movie generation is enabled, particles.mp4, particle_movie_frames, escape_summary.csv, plots, and movie.log.

Smoke Tests

Use tiny runs to check syntax and output routing:

cd /Users/thibaultclavier/report/simulations/inputs/model_1_hicks_proton
./run.sh --no-movie max_step=2 stop_time=2.0e-9 diag1.intervals=1

Repeat the same command from the other model folders. A successful run creates simulations/outputs/<model_name>/sim1/warpx.log and simulations/outputs/<model_name>/sim1/warpx_used_inputs.

The previous simulations/test_sim/outputs data is left in place as historical output and is not part of the active model launcher layout.
