Mesh and boundary conditions for three simulations (a) condition 2—LED mounted on a vertical offset of 3.5 mm to dental model A, (b) an LED mounted on an EVA shell with an overall thickness of 1.5 mm, and (c) an LED mounted on an EVA block with a minimum thickness of 1.5 mm. The impactor was simulated by a rigid plate rotated 0.1° about a reference point 630 mm directly above the LED.
