<p>PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which the microscopic surface shape of a fluid can be computed and in which a phenomenon due to a wetting operation and a repelling operation can be computed precisely by a method wherein the fluid is treated not as a continuous body but every very small region is treated as a virtual particle. SOLUTION: A fluid to be analyzed and an analytical condition or the like such as a boundary condition or the like are input from an input part 1 such as a keyboard, a mouse or the like so as to be stored in a storage part 2, and a simulation is executed in a computing part 3 on the basis of data stored in the storage part 2. That is to say, the fluid is treated not as a continuous body, but every very small region is treated as a virtual particle, the interaction of a force acting on every particle out of particles is computed on the basis of a function which uses the distance between particles as a parameter, a change with the passage of time of the position of every particle is decided, and a change in the shape of the fluid is reproduced. Alternatively, the interaction of a force acting on every particle is computed on the basis of a function in which the distance between particles is used as a parameter, a change with the passage of time of the pressure of every particle is decided, and a change in the shape of a fluid is reproduced.</p> |
