요약2 In this study, a model for predicting the grid quality of a building CFD model was developed using geometry characteristic index. Inverse topology count, surface area to volume ratio, and shape complexity were used as geometry characteristic index for the prediction of grid quality. Through the case study, geometry characteristic indices were calculated for a total of 37 shapes. The grid quality of each model was extracted. In the case of the inverse topology count, there was a high correlation with the maximum non-orthogonality. Multiple linear regression analysis was performed using the case study results, and a grid quality prediction model was developed through this. Two prediction models were derived for each grid quality, and both were evaluated as statistically significant. In the case of shape complexity, it was not derived as a significant factor in the grid quality prediction model. The adjusted R2 of the prediction model for the maximum non-orthogonality, and maximum skewness was derived as 0.738, and 0.806, respectively
