What are numerical methods and why are they important for engineers?
Definition and examples of numerical methods
Numerical methods are algorithms that use numerical calculations, such as arithmetic operations, interpolation, differentiation, integration, linear algebra, etc., to find approximate solutions of problems that cannot be solved exactly by using analytical methods, such as algebra, calculus, differential equations, etc. For example, finding the roots of a nonlinear equation, solving a system of linear equations, integrating a function over a domain, finding the eigenvalues and eigenvectors of a matrix, etc., are some common problems that can be solved by using numerical methods.
Applications and benefits of numerical methods for engineering problems
Numerical methods have many applications and benefits for engineering problems. Some of the applications are:
Modeling and simulating physical phenomena, such as fluid flow, heat transfer, stress analysis, etc., by using numerical methods to discretize the governing equations and boundary conditions.
Optimizing the design and performance of engineering systems, such as structures, machines, circuits, etc., by using numerical methods to find the optimal values of the design variables that minimize or maximize a certain objective function.
Analyzing and processing data and signals, such as images, sounds, vibrations, etc., by using numerical methods to perform operations such as filtering, smoothing, compression, encryption, etc.
Some of the benefits are:
Numerical methods can handle complex problems that are otherwise intractable or impractical to solve analytically.
Numerical methods can provide accurate and reliable solutions within a reasonable amount of time and computational resources.
Numerical methods can be implemented and tested easily by using software tools such as Matlab, Python, Excel, etc.
