Document Type and Number:
WIPO Patent Application WO/2023/121336
Kind Code:
A1
Abstract:
A method for constructing a reduced-order model by mixedly using linear projection and nonlinear projection schemes according to the present invention comprises: a CAE analysis step of performing CAE analysis for an operating condition of a facility of interest in order to perform initial condition analysis; a POD model construction step of constructing a POD model by using data of the CAE analysis performed in the CAE analysis step; a POD model error calculation step of calculating an error between a predicted value of the POD model constructed in the POD model construction step and the data of the CAE analysis; a higher-order error grid extraction step of extracting a higher-order error grid from the POD model; an artificial intelligence model construction step of constructing an artificial intelligence model by using data extracted in the higher-order error grid extraction step; and an entire data interpolation step of interpolating data for an entire domain by using a predicted value of the artificial intelligence model constructed in the artificial intelligence model construction step.
