A second derivative of a second-order differential equation is calculated at a reference variable value. The second derivative is multiplied by an analytical small variable value, the first derivative at the reference variable value is added, and a result is output as a first derivative after an increment of the analytical small variable value. The first derivative after an increment of the analytical small variable value is multiplied by the analytical small variable value, a physical value at the reference variable value is added, and a result is output as a physical value after an increment of the analytical small variable value.
