How to set the perfect matching layer for laser cleaning？

You can set it up as follows:

1. Define calculation area: Determine the size and shape of the area to be simulated.

2. Create PML layer: Select the appropriate PML layer based on the selected simulation area and type, and set the thickness and parameters of the PML layer.

3. Add PML layer to the boundary of the calculation area: Add PML layer to the boundary of the calculation area to absorb all laser reflections.

4. Set PML parameters: Set the absorption coefficient and conductivity of PML according to simulation requirements.

5. Simulation calculation: Start the calculation and observe whether the simulation results are affected by boundary interference. If necessary, adjust the PML parameters.
