Abstract
A topography simulation apparatus includes a processor and a memory connected to the processor. The memory stores instructions executable by the processor to set a function indicating a position relationship between a point in a calculation region and a material surface in the calculation region. The memory stores further instructions executable by the processor to determine whether or not a particle moving in the calculation region collides with the material surface, and update a value of the function, responsive to determining that the particle collides with the material surface.
