TOPOGRAPHY SIMULATION APPARATUS, TOPOGRAPHY SIMULATION METHOD, AND TOPOGRAPHY SIMULATION PROGRAM
First Claim
1. A topography simulation apparatus comprising a processor and a memory connected to the processor, the memory storing 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;
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.

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.

15. A topography simulation method comprising:
-
setting a function indicating a position relationship between a point in a calculation region and a material surface in the calculation region; determining that a particle moving in the calculation region collides with the material surface; updating a value of the function, responsive to determining that the particle collides with the material surface; and outputting a changed topography of the material surface based on the updated value of the function. - View Dependent Claims (16, 17, 18)
