How to run a new simulationΒΆ
After compiling the code, the
WarpX executable is stored in the folder warpx/Bin. (Its name starts
with main but depends on the compiler options.)
In order to run a new simulation:
Create a new directory, where the simulation will be run.
Copy the executable to this directory:
cp warpx/Bin/<warpx_executable> <run_directory>/warpx.exe
where <warpx_executable> should be replaced by the actual name
of the executable (see above) and <run_directory> by the actual
path to the run directory.
Add an input file 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. The different parameters in these files are explained in the section Input parameters.
Run the executable:
mpirun -np <n_ranks> ./warpx.exe <input_file>
where <n_ranks> is the number of MPI ranks used, and <input_file>
is the name of the input file.
