A visualization software for evaluating computational fluid dynamics (CFD) results was developed. Recently, progress of computer performance and CFD software enables to execute large-scale computation. However, the results of these computations tend to be enormous and difficult to be evaluated in detail. In order to reduce those results, proper orthogonal decomposition (POD) has been investigated. A small set of simulation results is analyzed by POD and grouped by the indicator of eigenvector. In this study, a visualization software for POD results was developed and applied to the unsteady flow analysis results of a optical disc drive model. The original results were reduced to 30% of original data and efficiently visualized by using this software.
