A computer system for simulating physical processes using lattice Boltzmann-based scalar transport that forces Galilei invariance for scalar transport.

摘要

PROBLEM TO BE SOLVED: To provide a technique for a scalar solution method in computer simulation of a physical process. A system 10 including a flow solution and a scalar solution includes a server system 12 and a client system 14. The server system 12 includes a memory 18, a bus system 22, an interface 20, and a processing device 24. The mesh creation engine 32 and the simulation engine 34 are in the memory 18. The simulation engine 34 includes a collision-interaction flow particle 34a and a collision-interaction scalar particle 34a', and evaluates a flow solution 34c for fluid particle collision transport and a scalar solution 34c' for scalar particle transport.
