How to run a new simulation

After installing WarpX as a Python package, you can use its functionalities in a Python script to run a simulation.

In order to run a new simulation:

• Create a new directory, where the simulation will be run.
• Add a Python script in the directory.

This file contains the numerical and physical parameters that define the situation to be simulated. Example input files can be found in the section Example input files.

• Run the script with Python:

mpirun -np <n_ranks> python <python_script>

where <n_ranks> is the number of MPI ranks used, and <python_script> is the name of the script.
