A grid convergence solution computation system computes a computed value (Ahigh) Of high-order accuracy, using a single grid, computes a computed value (Alow) of low-order accuracy, using the same single grid, and computes a grid convergence solution based on the relation between the computed value (Ahigh) of high-order accuracy and the computed value (Alow) of low-order accuracy on an assumption that the relation between the computed value (Ahigh) of high-order accuracy, the computed value (Alow) of low-order accuracy, and the grid convergence solution (Aconv) is substantially constant regardless of fineness or coarseness of the grid. The grid convergence solution computation system computes a highly accurate grid convergence solution (Aconv) by using small computational complexity.
