Abstract
These days, CFD simulation generates enormous output data, as a simulation handle large scale and complicated phenomenon. In this paper, we try to show a fluid phenomenon with so called "particle path". Each particle has information such as a coordinate, a velocity and a pressure. A particle updates the information by searching the nearest grid point, and moves the coordinate to updated velocity. We actually apply this visualization method to show a wind flow. Generate some particles dynamically, then observe the particle motion. Now we expect that we can show this application on CABIN, and we improve various input method to show phenomenon effectively.
