概要

It may be assumed that CFD data is always quantitative. This assumption is based on the procedure of CFD. However, since most of data from CFD changes to some images by visualization in analysis process, quantitative feature sometimes disappears. Although this is filtering process, in the case that raw data is stored somewhere, there is no issue on the quantitative feature because the consequent process after the computation has reversibility and is not time-consuming. In additions, considering that useful information is frequently derived from these images, argument about quantitative characteristic may not occur. However, in the case of a large-scale computation, it is quite difficult to store the raw data. Usually, after several trials that several images or animations are produced, the raw data is often scrapped. Therefore, analysis from other viewpoints and a quantitative comparison become impossible, and we should consider a new procedure to store the data. In this paper, we propose visualization techniques via a comparison space.
