摘要

In the fast steady state field analysis method, the following processes are executed in a computer. First, the physical quantity of the analysis object is calculated through transient analysis based on an analysis execution module in which a differential equation including the time-derivative term is made discrete. A time-averaged value of the calculated physical quantities of the analysis object that are present in a set time width is calculated. The physical quantity of the analysis object calculated in step 21 for each time step is corrected by using a time harmonic order correction equation for time averaging with the calculated time-averaged value taken into consideration. After the physical quantity became in the steady state, the physical quantity of the analysis object in the steady state is calculated through transient analysis in which a differential equation is used. The calculated physical quantity of the analysis object in the steady state is displayed.
