This program is intended to reproduce the results from the preprint
"Error analysis of the Strang splitting for the 3D semilinear wave equation with finite-energy data" by Maximilian Ruff
The program is tested with Windows 10 and Python 3.10 and the following version of its modules:
numpy - 1.26.3
matplotlib - 3.5.1
tikzplotlib - 0.10.1
