Visualization treatment manner of 3 dimensional fluid data

摘要

PROBLEM TO BE SOLVED: To realize the visualization of a fluid moving state, its three- dimensional structure and a structural deformation situation by arranging minute surface elements on the basis of calculation results of an analysis object and preliminarily given visualization parameters and performing image display of the whole surface situation that is subjected to movable deformation on the basis of a fluid velocity field. SOLUTION: An analysis data reading part 2 reads position coordinates data and velocity field data and then, sends them to a data storing part 4. On the other hand, a visualization parameter inputting part 3 inputs a parameter necessary to visualization processing and subsequently, sends it to the part 4. An operating part 5 performs an operation necessary to the visualization processing on the basis of the analysis data and the visualization parameter sent to the part 4. Finally, an image generating part 10 generates a surface that deforms together with flow as an image pixel data on the basis of the position and permeability of all minute surface elements calculated by the part 5. Then, the data is displayed as an image by an image display device 11.
