Smart Mesh

[Antoniahuber]

📝 Pull Request Summary

Through the smart mesh dx, dy and dz need to be implemented as arrays instead of floats. Therefore the rest of the code needs to be able to handle those as arrays. WIP: If the mesh-refinement is enabled, their is some charge accumulation! If it is not used the simulation runs as usual.

🔧 Changes Made

• allow dz, dy, dx arrays in grid, solver, source, wakesolver
• write test for edge detection

✅ Checklist

• Code follows the project's style and guidelines
• Added tests for new functionality
• Updated documentation (mentioned in docs/ or included in examples/ and notebooks/)
• Verified that changes do not break existing functionality (automatic tests passing)
