Tutorial: First Run

Audience: new users who want to build and run DYNAMITE once.

Goal: build and run DYNAMITE in Release on L=512 grid and inspect outputs.

1. Build:

   ./build.sh
   

2. Run a short simulation:

   ./RG-Evo -m 20000 -L 512 -l 0.5 -D false
   

3. Inspect outputs:

4. Explore the output directory printed at start

5. Open params.txt for parameters and environment
6. If HDF5 was available, inspect data.h5 (e.g., with h5ls/h5dump)

Troubleshooting

• Missing Grid_data/<L>: generate it with the grid subcommand. Example for L=512: See:
  • Tutorial → Generate grids (quick start)
  • How-to → Generate new grids (full flag reference + validation)
• GPU errors: retry with --gpu false
