Several other similar procedures are generally employed to check the accuracy of the numerical solution. Consider, for example, the dynamics of a moving body whose displacement x is governed by the ODE dx/dt = F(x, t), where t is time and F(x, t) is a given function. We may assume that the analytical solution is not available, since if it were, there would be no need to solve the problem numerically. However, the numerical scheme 21 Computer Methods for Engineering with MATLAB ® Applications 22 may be employed to solve a simpler equation, say, dx/dt = –ax + b, where a and b are constants.

Then the implicit methods, which usually do not have such constraints resulting from stability considerations, are ­preferred. Thus, the numerical instability of the method is an important ­consideration in its selection. As listed before, several other considerations also play an important role in the selection of the method. These include simplicity in programming, versatility of the method, computer storage needed, and interfacing with available software. In ­engineering applications, the simplicity and versatility of the method are very ­important, since interest often lies in solving a wide variety of problems with the least amount of effort.

In ­engineering applications, the simplicity and versatility of the method are very ­important, since interest often lies in solving a wide variety of problems with the least amount of effort. This is particularly true for the design and optimization of systems that often involved a diversity of components and equations. Frequently, some sacrifice is made with respect to accuracy and efficiency in order to select a simpler and more versatile method.
